1979 Coupe-The Tangerine Machine

Looks like TM 2.0 is going to be even nicer than the first version.

Man buddy so sorry to hear this happened, I see its in good hands for the repair glad you made the choice to do in house.

Yeah, you're telling me Fidel. Thanks for the encouragement!

I think you made the correct decision in repairing the rest yourself. Like you said "you built the car the first time" so you would have never been satisfied with the results that a shop would have produced the second time around. They are not invested into the car like you are and would just not care. You can now get it done right and be happy with the overall outcome of the rebuild.

"Invested". In every sense of the word! I know we are right that I possibly could've been disappointed with the results if the body shop had done it. Besides if I had fronted the funds to fully fix it, that wouldn't have taught Jackson any lessons. You can't just throw money at things and everything is all good again (well some can and do I suppose)! He needs to feel the pain of looking at it until it's fixed and then paid!

It may just be that! Just not quite as all-original.

For my spraying this time, I am not nearly going to the extent that I did before with making a booth. I think I can get away with it by just having some air flow through. Winter can be a good time because it keeps the dust down. Unfortunately this weekend, we were just a little too chilly to keep some fans running and a door cracked. Last weeknd was beautiful too! Maybe next weekend to prime the panels!

So what did I do instead today?

I also verified that it wasn't the rear seal leaking. It was clearly the oil pan

It wasn't dripping but the front end looks like it was weeping a little as well.

To finish the day yesterday, I turned the engine over to remove the oil pan and see what was up.

Looking at where the pan gasket met the rubber seal, it looks like the gasket shifted slightly and partally squished inwards when it was tightened down. This must have been the root cause of the seep from the get go!

I had sourced the gasket I needed many months ago after we first noticed the leak. The one I had used came in the Felpro rebuild kit for the 2.8. This one is a NOS Ford one:

Token beauty shot before I put it back together next weekend. Any tips to help ensure a good seal on the new gasket?

After the engine was out, I could look a little better at what needed to be addressed. Square footage wise, not that bad.

I need to figure out where I can make my transitions as I do not plan to remove everything this time. For now, the upper firewall and cowl will get redone as well as most of the aprons and all of the rad support. I think the K-memeber will get spot touch ups where needed.

Here are some more pictures of the damage repairs and the other areas that will need the most attention.

Coming along nicely, good work brother.

[IDMooseMan]

As usual, I'm late to the party.

Darran, I'm so sorry to hear about the accident, but, like already said, at least Jackson and crew weren't injured. It looks like you're making fantastic progress, once again.

So, what will it be this time? Supercharger? Nitrous? Both? Neither? <-- Probably the best bet for now, right?

Not the kind of party I wanted to attend. I would have said no thanks!

I wish I could, but nothing different this time Craig. The next round will be a number of years in the future. I need to get on to other projects!

[82GTforME]

So in an effort to persevere and keep doing stuff, I was at it today.

In my usual way, I got distracted and did not go out to do the oil pan that I left off at. The weather was much nicer today. We just got out of a cold snap with a bunch more snow.

There was the perfect breeze to get the cross flow I needed with the big door cracked and the back door open with the fan on. Plus no dust! It was game on for primer!

I scuffed up the rust encapsulator I needed to on the metal parts.

I will use a plastic adhesion promoter before putting anything on plastics, PBA, bondo, paint, etc....

So I used adhesion promotor on the cover and gave the last clean before mixing up some 2k DTM primer up.

A little masking in the garage for the overspray. Dial in the gun and voila!


http://s1337.photobucket.com/user/82...npu6j.jpg.html

I let the fenders and hood flash and get dry to the touch. Then I flipped them over to do the other sides. I was happy with the way I laid down the primer The sheet metal looks good from the first look over. The cover still has some small work to it in places that you can see easily now.

[82GTforME]

Okay, so I was done a little earlier than I had thought and I did take a look at the pan gasket.

From what I remember, the one that came with the Felpro rebuild set was cork and I know I had to trim it a bit where it met the seal.

The NOS Ford one looks to fit like a glove! Nothing like OEM

http://s1337.photobucket.com/user/82...glcj6.jpg.html

The previous one never fit this good! Any tips for a leak proof install? RTV? Anything on the gasket itself along the sealing surfaces?

[Davedacarpainter]

Progress! You're timing your repairs nicely. Spring will give you the best temperatures for painting.

Getting things coated with primer is always a positive step forward for me. Seeing the initial repairs covered and ready for final blocking and sanding prior to paint helps me to start to see the light at the end of the tunnel. I get remotivated at that step.

Good job staying on it.

[Zap's 85 GT]

The machine shop recommended using the yellow 3M weatherstrip adhesive for gaskets you never want to leak. They wont leak or move but are a huge bear to clean if it ever needs to be redone. I'd still use Ultra Gray/Black in the corners where the hump seal meets the flat gasket.

This. I use a dab of RTV at the corners where the rubber seal meets the cork. A little under and a little on top.

Thanks Dave. I need to keep going. While I hate the "fill, sand, fill sand" vicious circle, if I lose momentum, I'd easily procratinate a month! I need to get as much as I can done until spring clean up hits!

Good to see you posting Zap! I agree with the RTV in the corners. Thanks for the info on the 3M yellow. Is it really required? Can RTV or some other sealant be used to ensure a "seal"?

Does the rest of the gasket really need anything? My old boss said the "old school" guys might have used a CopprKote type of never seize on cork but this NOS one seems to have a coating...that or it's not cork exactly.

Thanks!

[Mustang-junky]

In the past I have added a little RTV on the oil pan rails just to keep things in place, just a few dabs, but it's probably not necessary.

Jess

[Davedacarpainter]

Any news?

[82GTforME]

Well, even though I put a bunch of time in, the results never seem to really show the progress well!

I blocked all of the panels again. Not bad considering...


http://s1337.photobucket.com/user/82...oesmz.jpg.html

I used a good flashlight to check for any missed chips and less obvious defects and used glazing putty on what I found or what I thought needed help. All in all, again, not bad. I am not the best at doing this on the first attempt and it seems I have to do/redo a few times to get it right!

http://s1337.photobucket.com/user/82...qmq2m.jpg.html
http://s1337.photobucket.com/user/82...ygtkf.jpg.html

These are all blocked and cleaned up again now. I also used the red scotchbrite and scuffed up the inside of the fenders and underside of the hood to be ready for prime and topcoat/clear. I would say ready for primer on the outside. Ready for colour...maybe.

The front cover needs a little more work on the spot where the repair was done. It's tough to get into and around the belt molding lines to block properly to get it smooth. The rest is good though

[82GTforME]

Jackson also helped me put the oil pan and gasket together. It seemed to go good! Funny, I checked the 79 repair manual to ensure I did not miss anything and the procedure actually states how to do it with the engine in the car!! So flip it back over to dust and re-detail it again and the engine is done...again.

[82GTforME]

I forgot to mention that I made an attempt to remove/hide the stamp on the repro fender.


http://s1337.photobucket.com/user/82...detff.jpg.html

You could feel it with your fingers so I hammered the deep stamp from the backside first with a steel block on the top, then used a drum stone to remove some material without thinning it too bad. I think it's pretty good after sanding too. We'll see with the next coat of primer. Some will be hidden by the fender bolt washer too.

My painter cleaned up the stampings on my reproduction trunk lid too. He just used a bit of putty to fill it in after knocking down the high spots. I assume he will do the same on the hood and fenders when he gets to those.

[84StangSVT]

Jackson also helped me put the oil pan and gasket together. It seemed to go good!

I see you are having him get his hands dirty this time around.

The repairs are looking good Darran.

[Davedacarpainter]

Nice work Darran, I can appreciate how much you've accomplished.

I thought of using a filler of some sorts also but being near the bolt and washer, I was worried that it would crack or shatter when it was tightened down.

Not a lot of help other than this so far but the timing was right when he came out and I had just put away the sanding gear and there was an hour until supper

Nice work Darrin, I can appreciate how much you've accomplished.

Thanks Dave. Professional body people get so much more done so much quicker than me! I'm in awe of their skills. Maybe I take a conservative approach or my perfectionist tendencies take over but man it seems to take me a lot of hours to get stuff done!

[JTurbo]

Looking great Darran!
