Diesel rebuild
Diesel rebuild
HI, how do you know when a diesel gq 4.2 d needs rebuilding?I am looking at one at the minute to buy, any sign to look for?It has 380000kms!Thanks
Re: Diesel rebuild
Smoke & oil consumption. If it is low on compression it will start badly, blow white smoke when cold or black smoke when hot but at 380 it should have a good few hundred left in it yet, mines up to 395 & is going strong, you can buy it if you likeesp22 wrote:HI, how do you know when a diesel gq 4.2 d needs rebuilding?I am looking at one at the minute to buy, any sign to look for?It has 380000kms!Thanks

additionally, bad bad timed knocking, phut phut noise ( both signs of either dropped top ring or gugen pin u/s), large lose of power....
at 380,000 you should still be able to see hone (sp?) marks in the bores.
Turbo it..
V8s are nice, but you cant beat the sound of a turbo working the magic on a juiced up diesel.
i have read about all these high km TD42's, unsure what went wrong with my mates, possibly bad service history.
just under 300000km and it took in a small amount of water and bent a rod, so we pulled it down and upon removing the rods from the crank all the top halves of the bearings where showing copper, so i guess we where lucky to catch it then.

That shows you how reliable they are, it should have been knocking its nuts off and had no oil pressure when the bearings are like that.
