1hz cracked head

[lshobie]

Ok, what would you guys do - I have a 2003 HZJ79, about 4600 mine hours on it, 600-620 psi on the cylinders, runs great, I've had it turbo'd for 3 years and have had no probs. It is getting hard to start in the winter here in Canada - I think the pump might need a rebuild. I'll have the tranny/transfer out of it for a rebuild this month, was going to take the engine out as well and swap it with a 1HZ from a 1991 HZJ73 Japanese import engine with low kms on it. I was also going to ceramic coat the manifold/turbo housings to keep the EGT's a little lower.

So because of the different precup design should I just keep my 2003 engine in it???? Either way it doesn't matter. My 2003 engine also sounds like a diesel, not like a 1HZ should sound, I was going to do a valve shim adjust on it - that and the injection pump and was hoping it would be quieter.

If I did swap the engines would I be into a head removal and new precup install???

Thanks

Check your glow plugs and wiring for them clean connections.
First thing to do.

New wiring harness, new plugs, new relay.
