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.......

[cvbikeguy]

sooo the parts just came in. got every thing i neeed. but...............


as i was taking off the rubber cover for the oil sensor i realized it was totally gashed....

huh?

anyways i was talking to my dad and he things we should just rig our own sensor like the was his GS is. i dont care really i just want to know things are fine. well i cant wait to finally get this done. started raining again so i cant work. but hell this will only take a snap.


thanks again for everyones help. this build has been taking so long ive already had time to start saving for the r154 swap

If you mean he's suggesting adding an aftermarket gauge and sender, well, that's an option... BUT, you'll still need to fix the stock unit... the ECU read it too.

Sorry.

[cvbikeguy]

Hmmm what do you mean? I can't put a normal gauge straight on the adapter without any electronics? This would just be temporary till I can figure out why my sensor isn't working (or whatever is causing my gauge to not work). The guy at the auto shop says it should be reading around 15 psi?

[cre]

The ECU requires an oil pressure reading within the same range as the stock oil pressure sender provides at any given RPM. Oil pressure senders provide signals which can vary greatly from one make and model to the next. you can run without the stock sender in there for a while but you may notice a loss in power and mileage. So, even if you do add an aftermarket gauge you do need to replace the stock sender (even if you don't use the stock gauge).

15psi is vague as hell... at idle? High or low? At low idle and at normal operating temps the oil pressure may be anywhere from 4.3psi to 40psi and still be within spec.... 4.3psi is the minimum pressure at normal operating temp and warm idle. The oil pressure you're really after is 3KRPM and above; You want 36psi+.

or maybe its the transmission?

Pull the spark plugs.
