I will stay with the 4.4 thanks- spent a long time looking for one in the uk and I hate the 4.6 (we have plenty here, lots of liner problems) but each to there own :)Quote:

I thought you'd say that, and fair enough. But once Turners have been at a 4.6 you aren't going to have any liner problems. Maybe you could keep them in mind as a back-up in case the P76 donk doesn't work out.
You know, it's funny but people have been running these engines on unleaded for years and they seem fine. Usually, the big thing with unleaded was not to flog the engine too much. It depends what you're planning. If you're going for a super-duper rebuild then it won't be a big deal to get the seats replaced. Otherwise you may as well leave the seats alone and use some additive if you're happy with that.
Thanks Dave, yeah the thing is after turners have been at it I will be at least £2400 +++ poorer too. The p76 lump only cost me £400 so if I can drop it in after some mild fettling it should be good to go :D IF not the parts actually seem cheaper than the uk for you lot :DQuote:

Just as point of note they have now been saying over here that the top hat liner solution on the 4.6 etc is no guarantee of a solved problem and several of the builders are irontiting the engines after the re-build to try and prevent warranty issues- that smacks of desperation to me lol :p
I rebuilt a 4.4 to a 5 litre many years ago.
The crank was machined to suit holden bearings and new liners pressed in to suit 202 holden pistons. It was 20 years ago so the details are a little vague but from memory I also used holden lifters. Holden parts are available anywhere. Oh, head gaskets were 3.9 rover ones.
The problem will be finding a good 4.4 with a good crankshaft to start with.
Crankshaft Rebuilders in Melbourne did the machining and may be able to help with some useful information.
Thanks, I hope the cranks ok for range rover duties I am trying to keep away from the 94mm bore you went to but I am sure it was a great engine.Quote:

Hi guys, what do you think of these brands for quality?
QH, NAK and Clevite.
There is one in a yellow packet too, any ideas what that brand would be?
We dont have any of them over here lol

Hi All
The 92 Rangie I purchased in March was from a bloke who had Half a dozen P76
at his place including a original Targa Florio ...... magic :)
He belonged to P76 Club and restored engines for the club.
He mentioned he had 40 x 4.4 V8 engines in his shed ....been collecting P76's since he was 18 .....now in his late 40's
I have his phone number ....great guy will ask him about sourcing parts for rebuild or an email address for advice.
