Ive just completed a quick repair build on my 22RE. At first it was to be an upper end deal but after 150 miles I picked up a small knock on the bottom end.

(The quick build was a head job, T-chain, T-chain cover and water pump. I checked the oil pump clearances while apart and it was in spec.)

Yesterday I pulled the front diff and oil pan. Found #1 rod bearing well worn. #234 were worn but still good.

I replaced the 4 con rod bearings. The crank was good.

I was expecting a notable jump in oil pressure but it was almost unchanged.

No problem as I attempted to hook up my oil pressure gauge but cannot find the correct fitting to addapt to the oil pressure port.

That said, I would like to know where some of your oil pressure gauges ride at idle and at highway speed.

Mine is a 94 22RE with 120K on the ticker. My oil pressure gauge has 4 sections between L and H. No numbers, only unevenly divided sections.

Any info will help. Thanks

^^ nice link, Thanks

However my current problem is I cannot find/do not have an adapter to attach my oil pressure test gauge to the block. It appears I will have to buy another gauge with new adapters.......nice.

I was curious where everyones oil pressure gauge rides to compare to where mine is currently at.

Are you talking about your stock dash board oil gauge? Or an after market true mechanical gauge? Trust me, it makes a huge difference on getting real oil pressure numbers.....

I am talking about my dash gauge. I know it isnt as accurate which is why I went for my diagnostic oil pressure gauge first, just dont have an adapter to fit a Toyota.

I would pick up a new one this week but have Church all week and will be heading to Alabama next week for the entire week to help build a church.....

Not going to have time to go pressure gauge shopping for a while.

I just bought a SunPro oil pressure gauge (made by SnapOn) to install in our '91 3.0. They also make/supply metric adapters to fit foreign engines. So you may wanna check their website and see about having one shipped to you. It shouldn't be that expensive......

This thread: https://www.yotatech.com/forums/f116...ge-how-103832/ says the block is threaded for 1/8" BSPT ("British Staight Pipe Thread"). Autometer sells such an adaptor here: http://www.autometer.com/cat_accesso...il.aspx?vid=59

I've never used it, so I would appreciate hearing from anyone whether this works. It's hard for me to believe that a Japanese truck would have a BSPT fitting. (For that matter, it's hard for me to believe that anything would have a BSPT fitting!) It may be "close enough" that a suitable amount of teflon tape and judicious torque will make it work.

I put a t fitting off the block which goes to factory sensor and an after market gauge. I got the fittings at an auto parts store and hardware store so they aren't too hard to find. I believe they were bspt, they were definitely tapered. My tired 87 is in the 40 to 70 range on the aftermarket gauge.

I ran by an old dealership I worked at a few lifetimes ago and got an adapter. Oil pressure is in spec but on the low end of the span.

In a fit of luck, I found the owners manual in one of the rear compartments. (check out the new members section to see the story behind this recently purchased truck)

According to the owners manual, the gauge is roughly correct when compared to the oil pressure readings.

This engine was patched to use the truck while I consider my next engine move. Build up a 22RE or replace with a stock 1996+ 4 banger.

It is a 1/8" BSPT (British Standard Pipe Thread, to be exact) and that adapter is what you'll need.

I stand corrected.

Apparently the T in BSPT stands for "tapered" (not thread), as contrasted with BSPP ("parallel") for a straight thread. Which makes much more sense for an oil-pressure fitting.

And despite the word British, it is apparently common in Japan. http://pipeandhose.com/?q=node/2
