yep,same 3.4l engine. i think it's a bigger problem in the vans,alot more stress on the engines pulling all the extra weight around.

yeah,i won't be stumped if it happens again,haha. this is one of those you don't forget.

wasn't bad. UIM stayed on. had to remove the left side engine strut-mount,coolant by-pass. but being the front side,it was pretty good access.

so,after the heli-coil for the rocker arm bolt,couple miles of driving,all codes cleared,runs super,like a brand new van,compression now reads 160-162 on all 6 cyls. cyl 4 specificly,is now 162. :bounce: and thank you everyone who chipped in with thoughts/opinions, you all helped alot,kept...

nope,valve spring is good,as are valves. just the rocker arm bolt backed out,slightly stripping the bolt.

i can get new heads for $170 each,the machine shops will probly ask nearly the same. i'll look into it though.

spot on man,i just discovered i can pull the rocker up & probly out with a magnet through the oil cap. it's gettin heli-coiled for now,when i get my tax refund,i'l buy a new head from autozone,and just rebuild the top end.

well,got bored waiting for the air compressor,and got an idea. since it's raining/snowing,i can't pull the valve cover today. so,i pulled the oil cap,grabbed a mini-lite & a micro-mirror. the cyl. 4 rocker arm isn't even moving. so i guess next nice day,valve cover's comin off...so,place your...

TDC should be both valves closed i believe

shouldn't i do the leak-down test first though? and from what my haynes manual is saying,i have to remove a coolant hose,and drain the system to remove valve cover...

loan-a-tool leakdown tester from AutoZone,and found an air compressor to borrow,gonna pick the stuff up tomm.,and see what we get...

Yeah,i kinda think it's a valvletrain issue, i doubt the HG,as it Never even gets hot,no oil coolant loss or burning. Guess it could be a piston ring,but i'm thinkin sticky valves or bad lifter,maybe a rod issue if someone else did the intake mani's,but the look like theyve been there for a...

well,big problem...i have no air compressor. i guess it'll go to a shop,and sit there till i get my tax refund... don't know what else to do. i figure an air compressor ect. will cost as much or more than paying a shop to do a leakdown test...

also,i did verify cyl.4 fuel injector IS working properly,as well as good spark,got ahold of a spark tester. what to do now? :dunno:

here's the results...
