Survivor
 

ok so I bought a unrestored survivor if I pull the engine to replace the timing chain is it still considered a true survivor the nylon timing components scare the hell out off me

Replacing normal wear items is completely acceptable but resist the temptation to "fluff" the engine compartment while you're doing it. What kind of car did you get? Everyone will want to see pics too!

Pics!!!

Yes, those OEM camshaft gear nylon teeth are scary.

As stated above, don’t disturb what’s left of any factory paint on that cover when you do the R/R on the chain unit.

What model, year and mileage is on this Survivor car you have?

its a 68 z 57000 miles I will post pictures of the gear when I get it out, was not going to not pull the engine but I think that is the best way to do it

Is that Corvette bronze?...Joe

yes no rs but kind of a high optioned Z

Cool. I have one of those also. Bought it in march of 1976...Joe

Very cool car

You can do a chain/gear change in the vehicle but getting the front cover back on with the pan installed is a MAJOR PITA and the front pan seal/gasket will likely leak. Pulling the pan along with the cover is the only way to get everything clean and leak free.

Awesome find!!:Can-I-Have-It: As others have said, no paint or fluffing!!

When I was young this was a routine job in the dealership, on any small or big block.

Two approaches,
1. Crack the pan bolts loose except at the rear, carefully leverage the pan down far enough to R&R the cover. Re-use the front pan seal with some discreet sealer, a little more at the corners.
2. Don't loosen the pan, pry the cover off, trim the corners off the inner cover pan seal channel (I know!! :eek2:). Use original pan front seal and discreet use of sealer. Use a drift punch on each side to leverage cover back into place.

If done properly, no leaks. Use OEM or black cover gasket, NOT a blue Fel-Pro!

It would be wise anyway to pull the pan to clean any remnants of nylon that may compromise the oil pump.

Looking forward to seeing this Survivor front to back.

Which means a LOT of cleaning with carb cleaner, brake cleaner and then acetone before the sealer.
Yes, did a number of them this way, but they ALWAYS seeped in the corners...:mad2:

I am going with the remove the engine and do it so I don't have any leaks I have done them in the car and yes it is a mother and it will leak

I am getting ready to do my 71 LT1... according to the guys on the NCRS boards I am living on borrowed time.
I picked up NOS timing cover and NOS oil pan gaskets and plan on just doing it in the car - I will use a piece of card board laid out for bolt locations when I pull the bolts so I can get them back into the same exact placement.

Wow, with the tilt hood, that is REALLY going to be a PITA job. It's hard enough laying over the front.
I wish you well...:worship:

My 1980 vette rounded a lobe on the cam on the way back to college in the early 90's.
The next morning down in the fraternity house parking lot --- I got an early jump at about 6 am and was breaking the cam in by noon.
This should be a much less hectic job! :blush:
