I never did this before and need a sanity check. I've seen videos that suggest to me this is OK but I dunno.

This is a pan off a mid 70s 'vette I bought off this forum and it measures 2 3/8" deep. I used a Fel Pro OS 34510T.

I see I put too much RTV in the corners but is that much of the gasket supposed to be visible like that? It went on easily and I used a torque wrench to give it 20 ft.lbs.

It just doesn't look right to me and as I said, I could use another set of eyes. Thanks

 

regardless of year

If you measured pan's Front Flange to be 2 3/8" Deep,
then it needs Thick front section, and
thus, OS34510T is correct.
Yes, it's a tight squeeze

* If you loosen/take it down, you Must strip every tidbit of RTV off of everything, everything like new, clean as a whistle, and begin all over.

** yours probably came w/ new bolts + washers ? did you use them ?

 

And did you check damper's snout for any groove worn into by timing cover seal's Lip ? That's a common cause of Leak too. Snouts' groove can usually be successfully repaired with a 'Timken Redi-Sleeve' or equivalent

 

Thanks guys. I just measured it again and it's definitely the correct thick seal. The pan was corporate blue before I painted it which is another clue I have the right gasket.

Yes, I did check the damper snout and its clean as a whistle. I used an offset seal for the rear main and understand what to look for. I'm using a new Allstar Performance cover and Fel Pro TCS 5124-1 with a new seal.

The Fel Pro OS 34510 T comes with a nice set of black oxide hex bolts with star washers. I'm using black oxide ARP hardware on everything else anyway. The four plastic corner posts to aid installation are slicker than a gravy sammich, this went on very easily. I had no problem threading the bolts in by hand or fitting it in, when I tightened the corner bolts down I felt the pan lock in with a 'snick'.

Just overthinking it because that gasket is so prominently BLUE . Whoever installed the leaky old chrome pan I replaced must've owned a nuclear powered RTV applicator and I guess the contrast it kind of threw me off. I inspected all of it it very carefully and call it good. Better than underthinking it I suppose.

I'm waiting on my new DeWitts rad, HiFlow Performance exhaust and a bunch of small stuff. I'm hoping to fire it up and break in the new cam before the end of the month
