89 4runner 22re.. 200k miles.. Timing chain broke. we pulled off the head and replaced it with a new head, did the timing chain at the same time, new timing chain cover..
The truck starts and runs ok, then as it heats up it starts to hesitate a bit and stumble.. we played with timing and the idle air control till we got it to run better.. Now when you twist off the oil cap the engine starts to die out and it has quite a bit of pressure coming from under the valve cover..
a freind of mine is telling me that it has to be the compresssion from the cylinder escaping past the rings/valves and getting into the oil cavity..
i did a compression test (this is at 6000 Feet in elevation)
#1 - 125
#2 - 115
#3 - 120
#4 - 120
any one have any ideas??
This is my first time digging into an engine, so wouldint be supprised if i F*cked something up..
no oil leaks.. Minor Vapor comming from the exhaust.. I put the Head Gasket on without any RTV or Sillicone..
