I'm in the middle of a timing chain and head gasket replacement on my 22RE. I'm at the point where almost everything is clean and I am about to reassemble. I have a timing chain and head gasket kit from engr bldg but I can't figure out where these gaskets go. The ones that are numbered I'm sure I'll be able to figure out one I get going, but the ones lable A, B and C I can't seem to match up anywhere. Thanks.

No one? I figure out most of them by now, but could someone please help with the gaskets in the third picture labeled A, B, and C?

a and b look like the EFI upper/lower intake plenum gaskets, and the c looks like the lower section of the carbutated intake for the water jacket. 2 and 3 in the first pic look like the carburated fuel pump gaskets. 1 is the gasket for the air injection tube that attaches to the exhaust manifold. it goes between the injection pipe and the tube that runs around the back of the motor to the egr valve. theres also a similar one that you have labeled throttle body that is for the oil pickup tube.

Third picture:

A = gasket between the PCV oil seperator plate and valve cover (inside valve cover)
B = same, but for a different year.

You have to remove the riveted plate on the underside of your valve cover to replace it. We do it here at the shop with every engine we build since it is UBER crusty inside and it has to be removed for the valve cover to be properly cleaned



C = for carbureted trucks only, it's the plate un the underside of the intake manifold.

C is for the water pump

when putting the motor back together.. anytime metal is meeting metal, there should be a gasket in between.. and they are a near perfect fit.. just go slow and match up gaskets worse case scenario

Sorry Blue, I'm not trying to be a know it all dick, but that is the gasket is for the intake manifold on carb'ed trucks (the plate that goes on the under side of the intake manifold, under the carb).

not trying to be a prick....

here is the water pump gasket

A & B are used for the valve cover / pcv / oil seperator (see 2nd thumbnail)

ohhhhhhhhh good call.. no worries putney, I'm not an expert, I just thought C looked familiar from when I did my waterpump a few months ago.. Gotta admit they look similar.. the oblong shape stuck out in my mind..

now that I re-read the thread, i see that you already said it was part of the intake manifold in post #4

D'oH!

here is the other (what gaskets A & B are used for)

was wondering why i had those gasket left over, had my valvecover dipped with my block on rebuild, how the hell you supposed to get that plate off an re-rivet it?

DupermanDave

I never knew that was there either. I just did a top end rebuild and never messed with that gasket.

we remove the rivet heads with a chisel to jet-tank the v/c and sheet metal. We then drill out each rivet hole and install screws. It's labor intensive, no fun and usually results in a few cuts on knuckles from the sheet metal part (look close at the picture, you can actually see the clean spots inside the valve cover from where I wiped the blood off).

It's the only way to get them clean. No fun, but it's gotta' be done.

Nuke

Thanks all.

So does anyone want to buy gaskets A, B, or C?

iTrader: (1)

2nd group of gaskets are egr (head/intake) and the plate on the rear of the head. don't know what the round ones are.

DupermanDave

Use them as bookmarks for the chiltons/haynes manual. That's what I've been doing.
