Ok so I just recently got a 4bt, Im going to go through it completely and this winter start swapping it into either a Dakota or Wrangler (still undecided).
I started a thread on 4btswaps.com for all my questions and I've gotten nothing but sh*t from those guys, everytime I'd ask a question the tell me Im an idiot and tell me to read the stickys
While I've never been inside a diesel motor like this before, I've done a lot of automotive stuff and I've got my trust service manual, so I have an idea what Im doing...still a lot of questions and advice Im looking for though!
To catch CF up, heres where Im at:
Brought it home last week, its a 2002 4bt from a small piece of construction equipment. Has low compression in cylinder #1. Has an inline A-pump (very similar to P-pump from what I've read). I also got an NV4500 and adapters from the guy, as well as 2 exhaust manifolds, a brand new turbo, and a few other small parts...
My fiance's been painting these murals in the garage...finished this one just in time!
Some more pictures of it on the engine stand
Took the valve covers and rockers off, and the other small parts to ready it for removing the cylinder head:
And the head is off. Head gasket looked decent enough, however it did look as if coolant had been leaking into cylinder #1, so hopefully thats all that was causing the low compression.
Flipped it over and removed the oil pan:
So as for my questions, here goes...lots more to come Im sure:
- Should I remove the pistons and check/replace the rings? I'm tempted to, however the guy at the local Cummins place told me he adheres closely to the "if it aint broke, dont fix it" motto...meaning he says if it doesnt look like I need to pull em, I shouldnt. Cylinder #1 is a little rusty/scaly inside the cylinder towards the top. Could I just clean it well enough with a scotch pad and call it good? Or should I pull all the pistons and do the honing?
