Hi All,
So after 2 different compression tests my rough running engine and smoke machine has come down to 2 cylinders down badly in compression (Cyl 1&2). Runs beautifull when its warm, cant even tell there is anything wrong with it, but starting cold its got a bad misfire and blows a hell of alot of black, then blue, then black smoke.

Called a couple of engine reconditioners just to ask the question, and seems a full rebuild with me removing & installing the engine myself is going to cost about $4000...

Anyway, thought I would ask the question about what most people seem to do when their RD28t runs out of puff...

I realise it may only be a head problem, but its not worth just re-doing the head on a bottom end with 310000kms...

Cheers,
Shaun...
