Lost Compression on all cylinders, right side
My 1995 4runner, v6 shut down on the way home saturday. Had it checked monday and good fuel and spark, no compression on 1,3,5 cylinders. What would you check if you lost compression on all 3 cylinders on one side? Motor has 30k (rebuilt) and ran great all summer.
Compression on 2,4,6 was 140, 148, 140. Kurt

Re: Lost Compression on all cylinders, right side
Could be timing belt slipped a few teeth on that camshaft pulley.
Do a leak-down check and see where the air is coming out. Exhaust or intake valves, then it's timing belt. If its water jacket or oil filler, it's head gasket. (probably head gasket as fourwd1 said)

You were right Brian, timing belt had slipped 6 teeth, now to find out why?

Re: Lost Compression on all cylinders, right side
Probably a bad tensioner - Replace the belt and tensioner, make sure all the pulleys are clean.
