Low Compression and Timing off. More details inside help!
So i posted a couple weeks ago about how my 4runner 94 3vze 2wd wouldn't start
Well i had my mechanic look at it for free... I couldn't figure it out.
So the compression is under 100 and i do have fuel in my throttle body.
He said the compression is oviously low but he should be able to get it to start so he looked at it more.
He said the timing is badly off, which wasnt a surprise to me because there are a lot of things that need to be fixed on my runner.
So this is my predicament. He said they could get the timing back to normal for 300$ bucks.
Im trying to decide if i should pay them to do it or I was gonna attempt to do it (no experience) just have seen write ups.
If i did it i would replace the belt and maybe other things
But as i said the compression is low so the engine may go.
WHAT WOULD YOU GUYS DO? i can give more details if asked

What timing? Valve timing or ignition timing? If it's valve timing, the compression will be low BECAUSE the timing is off. $300 is a rip-off to fix either timing issues though.
To fix valve timing, you need to take off the valve cover (4 bolts), turn the crank until the timing mark on the pulley matches up with the 0 mark on the timng cover, and then loosen the cam sproket, and rotate the cam until the timing mark on the cam is also at its 0 position.
To fix ignition timing, you need a timing light, which can be borrowed from most auto-part stores. Jumper the test connecto for the motor, start the truck, and shine the timing light on the crank pulley. Loosten the bolt on the distributor, and rotate it until the timing mark is at the 5 mark on the timing cover. Tighten, and you'r done.

well its got to be the valve timing because they said they need to take off some stuff to do it. And he said it jumped badly if that makes sense to you.
thanks for the tips. im a newb, i learn how to fix my truck as things break. my basis of knowledge is from you guys. so when i sound like i dont know what im talking about, i really dont know what im talking about. Money is tight for me so i need to probably do it myself. I do love to work on things. its just knowledge, tools, and workspace are hard to come by.

might be a stupid question....
when you say take off valve cover, its the driver side one right? just because the other one is a pain to get to....
thanks for the help
