sooo i have been following the tsrm. i did notice the part about sealing the timing cover but i thought it was nothing. and honestly didnt quite understand. the rtv goes behind the rear timing plate (between the block and the timing plate? or since i can take the head off i can rtv on top of the timing plate? i did have the machine shop shave the plate along with the block so they are flush.

and for the timing covers i can just rtv in the corners as shown in the picture? also are you using stock bolts with the philips heads or did you get replacement bolts? i have new bolts but i couldnt find grommets like the original.

thanks so much for the help cre. i think this is exactly whatmy problem is. besides changing the distributer o-ring and figuring the electrical for my oil pressure sensor.

The RTV does go on top of where the plate and block meet. Put down about a 1/4" bead.... I'm pretty sure mine leaked because I put it on way too thin.

Get new grommets from Toyota or another parts shop if they have them... definitely use them. I'm using hex bolts with a flange head along with rubber/copper grommets I found at a specialty hardware shop. If you really want to make sure they stay in place you may add a drop of temporary thread locker to each of the bolts.

Still no oil pressure readings?

heyyy sorry for not having an update. i have classes just for a few weeks and i wont be able to resume for a little. the car is currently sitting in shame.

ok sooooooo. just to triple, double, quadruple check. all i need to do is take off the head. not the rear timing plate.

then put a thin bead on top in those two spots where the timing plate and the block meet.

hmmmmmmmmmm

since im going to be unable to work on it im also going to see if i can order new copper washers, no 3 valve cover, and a few other things.

Yes, pull the head to seal that area... it's just as much work the other way, harder to reassemble and you're likely to scrape the RTV out from where it needs to be when you put the plate back on.

Did you go with a metal HG or an OEM style composite HG? If you used a composite HG it needs to be replaced.

Don't forget the RTV at the #1 cam caps when you reinstall the valve covers.

I'd install new cam seals and new valve cover seals if you haven't already done so.

heyyy sorry im back from school. i had training for 2 weeks for my plumbing. i already have new seals and i have the no. 3 cam cover, copper washers, misc bolts and head gasket on the way. what area on the cam covers should i rtv? man im so surprised that its such a big deal to rtv that tiny space on the timing cover.

I linked to the TSRM pages where it shows where to RTV both timing cover and the valve covers a few posts up: http://www.toyota-supra.info/forums/78100-post243.html

Yeah, we don't use a lot of RTV on these engines but this engine's a bitch when you forget it.

man that sucks. i should have paid more attention. well i havnt driven it since my first run so hopefully everything is good. parts still havnt come in but it should take me long at all to do this after i get the parts. still cant believe a couple drops of that rtv can make such a big difference. cam covers definitely need it though. i heard of some people just putting rtv all around the covers, is that bad?

just remembered i forgot to get a new o-ring for the distrib.......
