Pulled the injector and it is not broke.. Also pulled glow plug and it is also not broken.

What should the compression range be? I would guess that the best way to do that would be to install new seals on the injectors? There was 3-4 of them that the bottom seal was in bad shape.

I should add that since I bought the truck it smoked some on start up, both warm and cold, but not till the last two weeks that it got worst, and about a week ago it go to there on deacceleration it would really puff the blue/white smoke...

 

... Compression should be above 325... 375 or so is good. below 300 is not so good...

 

Think I'm going to take the injectors in to get tested today... for $25 I would know if they are good or bad.. Can an injector go bad and flood a cylinder out causeing the rocker to be broken? Getting my o-ring seals today so I should be able to do compression tonight.

 

Ended up ordering 8 new injectors 4 flat out failed the test, and the other 4 had internal leaking and was told that they could last or they could not... Also ordered a few extra parts while I had the card out... Should have it all back together tonight!

 

well, motor is in the machine shop. it tossed the rings....

 

Sucks. .. Compression test kits are cheap, just for future reference...

 

yup. going to do a complete rebuild. figure the bad injector was part of what caused the problem...

its being cooked right now, hope to order kit tomorrow.

 

Order up some Forged rods while its down... No reason to throw PMR's back in there...

 

Taking heads in today, Intake valves are shot... Who ever had this truck before me treated it like crap. At least when I'm done I will know what I got.

 

what kind of money are we talking to have rings replaced on our motors? I need to check my compression asap
