Timing Chain Cover Questions.

**854vragtop** · 07-07-2013, 06:55 PM

Once your cooling system/block starts developing rust, it can be a real bitch to get rid of. Having gone through this before on one of my early Fords, I would go back to a 50/50 mix and buy one of these drain pans to stick under the area that's leaking. http://s1.cdn.autoevolution.com/imag...your-oil_5.jpg It should capture what leaks so you can strain it through a paper towel and pour it back into the radiator. And, it will keep any animals from getting at it. I use mine to carry used coolant to the local recycling center.

If it doesn't quite fit under your car, drive your front wheels up onto a couple of foot long sections of 2 x 6's.

Got some work done today and although not everything went as planed, I still made some progress. Got the damper and the cover off, and cleaned up a lot..man! was this thing filthy

Just as I started to put it all back on, the cover plate would not align with the dowels and I ruined a brand new gasket from the RTV drying out. So off it all went.. and got a new gasket to try again tomorrow. I figured out that the front oil pan seal that comes with the Fel-pro kit is way to thick, so I will be reusing the Ford that is shaped differently and fits better, and hopefully works out.

I would install a new double roller timing chain now that you have everything off. Your stock one looks like it has some slack. Cheap insurance IMO. From the looks of that fuel pump eccentric, i guess you have a left over 85 shortblock. I've only seen two other early production 86's that had a fuel pump essentric on a EFI engine.

What is the best thing to put on the cover bolts?
anti-seize, blue loctite or RTV ?

**FM2NOTCH** · 07-08-2013, 08:39 AM

that does look pre 86, did it have a fuel pump block off plate where a mechanical pump would have been installed? or is the hole in the timing cover just not opened up?

I say cover the whole bolt with antiseize

**TheWizard** · 07-08-2013, 09:14 AM

Not open is just a dead end hole, nothing there. But yeah definitely pre 86, built dates back to late 85 iirc.

Yeah I think that's what I'll do, hopefully they stay in place.
thanks.

The '88 Crown Vic 5.0L long block that's in my '68 Cougar also had the fuel pump eccentric, even though the timing chain cover had no opening for the mechanical pump arm.

Wow, Ford must had alot of left over 85 shortblocks.

No 'leftovers'. They intentionally built them like that into the early 1990s. If you look closely you will notice that the fuel pump eccentric on the OPs engine is only the 'inner' part of the 2-piece eccentric that was used previously.

**poetnprophet** · 07-08-2013, 02:15 PM

My 86 had the fuel pump ecc on the cam bolt, and an empty pump boss on the cover. I removed the eccentric when I changed cams.

+1 on the timing chain. $50 from LMR and takes 10 min to change now that you're there.
+1 on the sweet looking engine, too!

Mmm...i see that now. I wonder why they did this since no carbs were in used then, interesting.

$27.99 from your local Autozone. I've used these in 500+hp engine's with no failure.

Factory used the inner part of the eccentric with an assembly/pre-timing fixture.

**TheWizard** · 07-08-2013, 10:20 PM

While getting it all back up and glued together I kept losing the cap from the RTV

.. well, I found a cheap solution..

A wire nut..I got a box of those, I guess losing a cap is no longer a problem.

Thought I'd share.

**TheWizard** · 07-09-2013, 10:16 PM

Almost done, today I got most parts buttoned up. Tomorrow I'll bolt up the fan, change the oil and filter, refill the coolant, and say a prayer.

**TheWizard** · 07-10-2013, 09:28 PM

All done.. took'er on a long hard drive, no leaks (so far)..

Thanks to all of you hardcore foureyers here .......Ohh..well.. hell..all is well in my Mustang Werld..

**FM2NOTCH** · 07-10-2013, 09:39 PM

good job, now wait for the heater core to blow, LOL

Why's that?

**FM2NOTCH** · 07-10-2013, 09:52 PM

that would be my luck, have everything leak free and then the heater core would blow.

My heater core has been replaced, and if it does leak now .. I'll by-pass it.

If the feed hose from the intake manifold still has the restrictor in it, no worries. If it doesn't
still have the restrictor, put one in. Fox heater cores don't just fail for no reason...

Sadly..I learned this tip the hard way. On more than one car....

Here is a good discussion on heater core restrictor alternatives:

I chamfered the inlet and outlet sides of a nylon dowel from Lowes as described here:
