What am I doing wrong?

<< < (2/4) > >>

bilge rat:
seems unlucky to have this much bad luck with one fault,  the blocks should never give a problem with the head being alloy its that that takes all the stick , the rover head gasket is one of those multi plate type. i was told to stay clear as they tend to leak oil , (unusual for a landy) was advised to fit an ering one which was the old fitment. apart from that a good aftermarket would be just a s good . payne e.t.c. only thing i can ask which i know you will have checked is the torque settings , are you using the correct message and torque which im sure you are and the other thing is do you make sure the holes in the block are clear from oil and water before you fit the head and bolts.  iff theres any left in the bolts can sort of hydrolic when you torque them down which can screw things up a lot. is the p gasket o.k . apart from that cant think of anything else. iff theres anything ive missed or your unsure of give us a shout . alan.....

Sharpshooter:
Correct me if im wrong, but dont you have to measure the clearance on the pistons from the top of the block, and then use the correct head gasket accordingly. I remember seeing something about it.

I.E if you skim the head, you use a thicker gasket with more holes in it.

I will try to find the text.

davidlandy:
do you need to use new head bolts?

Range Rover Blues:
Both engines had new bolts yes, I don't recall which brand of gasket but they both looked the same, similar to the composite V8 gasket I'm more familiar with.

I cleaned the threads in the block before fitting the new heads too.

If it were one engine I'd just try again but it's both of them, perhaps the coincidence is that they both went at the same time, but then how many dodgy gaskets hit the market place?

Ummmmm, hard one that, there's Chinese imitation, there's Taiwanese imitation, there's Russian imitation.......

How many recalls are there from the motor manufacturers?

Looking at all the posts regarding this, it looks more likely that it's all coincidental...., as they say, if at first, try, try and try again....., or get a Jap......
