Got a question about the 3VZE Timing Belt Cover Gaskets.

I was wondering if they are supposed to be soft rubber or hard rubber.

Mine aren't brittle hard but they certainly aren't a soft rubber.

Just wondering if I need to replace them.

thanks

 

Their purpose is to keep moisture and dust off of the timing belt components. Which they do fairly well, so long as they're all still in one piece. I can't see new ones necessarily doing a better job than old ones that still work though. The ones on my 88 are still holding up pretty good. I haven't had to replace any of them yet.

Anyways, some of them are foam rubber and some are hard rubber. And they're not necessarily cheap either. There's 11 of them ranging in price from $.82 to $37.54 each. I'm pretty sure their compositions are as follows:

Foam rubber
11312
11349
11357
11358
11359
11359A

Hard rubber
11322D
11322E
11322H
11346
11347

 

Great, thanks a ton.
The ones I'm looking at are all the hard rubber ones you listed.
I'll just leave the current ones on and save the money.

 

I know this is an old thread but I’m running into this now as I do my cam and crank seals. The gasket on my backing plate is almost all the way gone and there was a bunch of dirt and moisture trapped behind the timing cover so my guess is that this is the culprit. These gaskets are discontinued from Toyota now does anyone have any ideas on what to use to replace it? I was thinking of just getting high temp self adhesive rubber stripping in place of it since it’s only used to keep junk out of the timing belt. Any ideas would be appreciated.

 

The Ishino-Stone valve grind set I bought, contained these timing belt cover gaskets.

 

If a rubber seal becomes hard or deformed you can sometimes get some of the softness and shape back by dropping it in a pot of boiling water for a few minutes. Turn the burner off just before you put the piece in.

 

Thanks guys
