geoffbeaumont Posted June 19, 2006 Share Posted June 19, 2006 What is it with Land Rovers? Wretched thing's blown a head gasket again Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 19, 2006 Share Posted June 19, 2006 Did you get it skimmed Geoff? I have some small experience with heads at present! Composite or shim steel gasket? I understand that as a second gasket it's preferable to use a composite. Les. Quote Link to comment Share on other sites More sharing options...

To the best of my knowledge it's the original gasket (tin) - this isn't the lump I did the gaskets on last year, it's the 3.5 we fitted after the 3.9 destroyed itself. Guess it's done something in the region of 115k now, so it's getting to that age. I'd bargained on getting a bit longer than this out of it, though Ah, well. I'm leaving her for a disco at the weekend... Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted June 20, 2006 Share Posted June 20, 2006 Composite is the way to go. Helps "Seal" where maybe things are not perect, but heads and block need to be very clean and without scores or damage, if there is then a skim will be required. But, a comp gasket can do it where a tin one gives up.... Also head bolts, need to be bolted in and torgued down in the right orders and torque, as do the inlet manifiold bolts which many are unaware of... I can post Diagrams for both if yer need, also use the later black valley gasket (needs different ends too) rather than tin one, and run antifreeze up at around 40-50% HTH Nige Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted June 20, 2006 Author Share Posted June 20, 2006 I've got the cylinder head bolt order, don't think I've ever seen one for the inlet manifold? I won't bother fixing this engine anyway - I'll either get rid of the truck or lay her up and start work on rebuilding the 3.9. Haven't decided yet.

DEANO3528 Posted June 20, 2006 Share Posted June 20, 2006 If you followed the manual to the letter then that is why it's blown again! Don't tighten the outermost set of bolts beyond 10-12 lbft or the heads tilt due to the uneven bolt positions Quote Link to comment Share on other sites More sharing options...

I got the bit about the third row bolts when I did that one - just managed to shear a head bolt off trying to reuse the old ones Quote Link to comment Share on other sites More sharing options...
