i accquired a 95 ram 5.2 88000 clean truck that has set in a field for 1.5 years. i figured a good tune up and redy to roll but ive ran into low cylinder pressure it wouldnt clear with normal remadies but i removed cat made a y pipe with a hole for o2 sensor. cat was clogged gonna drive some more. do you think sitting messed it up this bad or bad before parked. 3 cyl. has went from 30psi to 70 in 500 miles. next step tear the heads off. gonna do it my self 1st time. truck actualy runs good other than idle and loss of power gets 14 mpg. how much improvement would valve job do. you can switch 1 and 3 plug wires nd cant even tell. all injectors good

 

might just need a valve job, but it could also be a cracked head. you won't know for sure till you pull them off. when you put it back together consider a hughes plate for the plenum and a new water pump. your mileage is really low, timing chain may be good.

 

wouldnt there be any other sighns for cracked head ? the oil stays clean and dont use a drop no water in oil or vice versa. i can with stand a valve job but not new heads. im gonna drive another 300 miles and do a compression check. i check iac sensor today good

 

i would changethe oil and take it easy on her if hasnt ran for a while ,i would say tune up for sure , and check plenum

 

You should probably do an engine flush and do the suck-seafoam-in-the-brake-booster thing too. That might help if it's just a stuck/rusty ring or valve.

 

thanx for reply. ive done all that mmo in the plug holes breather. changed all fiuds and plugs cap rotor im drivin to work this week and see if it helps.

 

i havent done the engine iol flush i noticed seems to be really carbon up. black sticky stuff on every thing you look at. maybe cause the cat was clogged

 

do seafoam in the brake booster and if it sat for that long its going to be one hell of a smoke show lol http://www.youtube.com/watch?v=dTZ42U3qSts
but dont gas it like he did that beating on it and i9t will clean it. engine flush and new oil will be good too
