The problem with a big cooler is where to mount it...not impossible, just very difficult. Especially if you already have an existing IC set up that takes up a lot of frontal area. One other option is to add a fan to the cooler...like this one...

There is a PCV system...just no PCV valve ;) I'd check to be sure the TB orifice isn't clogged up, forcing oil vapor into the accordion hose side of the system.

Any codes?

Code 22 - It's the ECU coolant temp sensor in this pic:

You're welcome ;) A parallel circuit will split the flow and keep the line length (oil path) down. That CM filter spin-on is one of the best...use the 6 1/4" tall one if you can comfortably fit it...it flows 45 GPM. It will be easier to change vs the in-line one. The in-line offers no...

Coil spark plug wire order...left to right: 1-6-3-4-2-5

Like I said, I'm not trying to be a Dick. I answer dozens of oil questions a week via PM...it's just get old trying to drag info out of folks in an effort to help. 250 degs is still too high post cooler...I'd be interested in seeing the Blackstone results. With -10 lines you should be...

Ok..."measured at the filter" doesn't tell me squat...I have no idea how your filter/cooler circuit is routed. One more time, is that pre-cooler or post cooler temps. Temps at the pan are going to be higher...that is a pre-cooler temp...kinda the whole point here. And, you didn't tell...

Yep...RP seems to be the loudest right around 2500 RPM.

The main crank pulley...the one with the timing index mark on it...the bolt in the middle ;) It's called a dampner. Might want to listen to where exactly the ticking is coming from...a stethoscope would help. Not likely will an over full crankcase...especially for such a short time...

fonz - we don't need pictures of a CPS o-ring...I know what it looks like, and I know what a leaking CPS looks like on the head. Tell you what...take your cheap ass down to the Toyota Dealer, make yourself take out your wallet, and buy a friggin o-ring. Jeez, it's just not that much! No...

High compression is good for low end, even on a turbo motor. The problem with increasing piston CR on a turbo motor is the effect it has on dynamic compression when the motor is in boost....it increases...a lot. That makes a turbo motor more prone to detonation at higher boost...not good...

There is no PCV valve on a 7M ;) A gumby routed catch can or clogged TB PCV orifice will cause this though.

Nope...in fact, it's a very good idea. Running a quart over the full mark on the dipstick is cheap insurance against uncovering the oil pump pick-up...an pump that suck air just for a second at high RPM is a good way to cause rod knock. That's why we asked ;) Can you tell where on the...

The machinist can't adjust the valve stem length to bring the seat pressure to spec? 70# of set pressure *should* be more than enough to keep the valves from floating at those boost pressures.

Yep...the stock 7M TB is a 60mm bore. The Lex TB does not have the same bolt pattern though and does it accept a 7M TPS (or can the LEX TPS be wired for the 7M TCCS)? Another thing to consider is the TB opening in the 7M-GTE plenum...it would have to be bored. The Grp A 7M TB was at 67mm...

1st of all - Where are you reading oil temps at...i.e. the feed line to the cooler, the return line from the cooler, or at a block location? What kind of oil temp gauge? What is your pressure at idle and at 3000 RPM? Is the oil pump relief valve shimmed for more pressure? What is...

Code 12 points at the CPS or it's wiring. The wires around the CPS connector frequently become brittle...you may have to re-wire it. Code 24 & 31 are the AFM or it's wiring. Check the connector for a solid connection...it could be the wiring as well. FYI - both these codes put the ECU in...

No - the 7M has a noisy valve train in general. Valve tick is usually incorrect valve clearance or the cam caps are not torqued down correctly (bad).

fonz - the way you posted it led me to believe oil was coming from the inside of the CPS. The o-ring is the only external seal that keeps oil from flowing around the hole in the head. Yours is either old or the wrong size. You can purchase some gasket material at a parts store and cut a...
