Did a compression Test. One Of the Cylinders. Kept rising in
Compression. i stoppped it at 200 what cuases The comprssion to Rise like that? and not stay at roughly 170 175?

sticking valves

carbon buildup other things

So basically i should Replace My valves? or just My exaust? what ya think?

um i dont think its the valves probably the carbon i would take the exh. manifold off and check out the port


you said only one cylider is doing it right?

is it running like crap?

Yes.

Yeah its Runniung like a bag Of shit.

i Took it for a boot just down The STreet There is Now power. what soever. like im driving a 4 cyclinder piece of &&^%*&

yeah take the covers off first did it just all of a sudden start running like crap or did it progress?

that will kind of tell you wut it is ........when valves stick they ussually just start running like crap (in my experiences)

carbon build up it feels like youve got a slight miss or less power

it all happen at the same time. My camshaft Lobes Slowly Died and cam was gone. and than the power Loss. so i changed My cam and Lifters. But its still running like Crap. i drived it a few times. untill i couldnt handle the Power Loss. So basiaclly i think im narrowed DOWN to my Valves? what do ya think?

when you change your cam and lifters you didnt take off the heads? i know you dont have to but i allways do just to see wuts goin on

well basically valves when you get a chance take them covers off that will tell you

i just notice you said your cam lobes went bad that tells ya right there that its somthing in the valve train

No i didnt Take them Off. i was told i didnt Have too. but i think there is something goin On with the Valves. specially the Exhaust. i dont Hear My cam comming out of my Mufflers. and before it Rumbled out those Pipes and i got a heavier Lift this time and i cant even hear the Lift. ya think my Exhaust Vavles are burnt ?

So i have to Take the Top part of the Motor off again> to Change The valves or is there and easier way around it? ir should i take the Heads off just to see whats goin on in there?
