Looks like carbon deposits from burning oil to me.

When you checked the compression, did you have the throttle wide open? 120 is low, but at least they are all even.

Guardian_Saint

120 PSI. Maybe check your timing is right. When mine was off. It was 120, 100, 120 on the driver side.

yeah the throttle was wide open......how bad was it saint? I was thinking to do that next.....do you think if by one tooth off would do this?

yayfortrees

If it is off, I would think any more than one tooth would cause some big problems.

But yeah, if your cam timing is not spot on, your compression will suffer.

Do a 3.4 swap!

norcal707

Ok, I have a few people telling to do the swap but it is too expensive for me right now. However, if I swap the engine, do I have to swap the transmission too.

9four4runner

i wanted to swap out to the 3.4 also but for us here in nor cal those engines are hard to come by i still cant find one and when i did the guy wanted like $2300 for it
i live in arcata north of you

The swaps are pricey, although I'm in the middle of rebuilding my 3VZE and I just hit $3k... I ordered a Super Stock rebuild from Oregon Engines, I'm doing a new exhaust and replacing numerous sensors, connectors, vac lines - etc. I should have just gone ahead with the swap... but a good 3.4 is difficult to find.
I don't think you have to change the transmission - at least thats the case for my automatic. There are several write-ups on swaps here. Take a look and see what you can find.

Both spocket was 2 to 3 tooth off. Got caught from the damage gasket from the cover.

That clip is like a bad porno... its all steamy, you can't really tell what you're looking at, and there's heavy breathing.

9four4runner

yea i know i let my block sit with water in one of the cyclinder and it rusted so i had to get an other block i spent about $1200-$1400 just on parts and macheing i did all the work so yea its a lot of money to rebuild a 3.0 but i think the 3.4 wont bolt on to 3.0 tranny but who knows im just a newbie im more of an AE86 guy

take your time and do it right...

if you rush it your just going to have problems...

norcal707

Jajaja bad porno...sorry matt16 I used my phone to made the clip.

Hey 9four4runner, after you did your rebuilt, did you notice a big different of power from the engine....

Hey loco, $3,000 is a lot. I bought this runner for $1000 and only have spend like $450 on it...right now I am just driving it to and from work..not even a mile from where I live...I am going to try to adjust the valves and the timing belt....however, I have been looking for the shims online and can't find them...

9four4runner

oh yea it felt the same way the day my dad drove it off the lot at the dealership ive seen people rebuild the 3.0 so i rembered some things an then i got a buddy to come and over look my work

9four4runner

but after i got it running i couldnt get the Fuel Pump or starter to work so i just got them to run off toggel and push button swichts

norcal707

how long it took you to rebuilt it?...i am thinking of rebuilt me in the future.

norcal707

you are right 1990yota pickup.....I learnd my lesson the hard way with my hg job I did on my runner.

9four4runner

all in all my runner has been MIA since Dec. but i got her to start and drive yeasterday
just the tear down of the block and getting the money for the Mshop was the worst part for me once i got the heads back it took me a day to get the heads back on to torqe spec and then the wiring took me a while then the vaccum lines were a pain

1990yota-pickup

of course iam right, iam never in the wrong...
