Head bolt re-torque

WLJayne · Mar 2, 2013

I don't think it's the inlet, it's had a new gasket very recently. You could chase problems until the cows come home - indeed I think the cows arrived many weeks ago and I'm still at it. But I think the problem is the whole bleedin' engine, and it makes sense to just put another bugger in.

James will correct me if i am wrong, but dont the liners get fitted from below, clamped by the rail?

The liners fit from the top , they have a around or just below 1/2 way down that sits on a ledge and the fancy Land Rover sealant is just Blue Holamar as used by Rolls Royce etc

Thanks JM. I just missed a totally immaculate 328 SE. Well I didn't really miss it - wifey would not let me buy it, but you know what I mean and now its sold. Silent at tickover, nice roar when revved

Very interesting. So liners can be level with surface!

Cylinder liner position
Cylinder liner position is the distance that the liner protrudes above or is below the face of the cylinder block. Liners can be level with or 0.075mm (0.003in) above the face of the block. If the liners have dropped below the block face, the engine must be replaced.

I think they changed the liner height specn

Mine were very slightly proud, 0.1mm or so. Maybe DD and I were right at the time in thinking that the bolts weren't tight enough? I doubt they've even been tightened to yield!

NOTE: The cylinder liners of the K series engine are a slip fit into the block. Free
rotation of the liners is normal

i made sure mine dint move when i took the head off but the tech bulletin says that it is normal for em to rotate,

shirley that is allowing free movement, though not lateral, to the liner.

all a bit dodgy if you ask me.

if they were free enough to rotate they leak past the fire ring ,not everything written is based on reality

Scathing doesn't even begin to describe that

! Nothing untrue, sadly. BUt then all cars are **** in one way or the others. Honda's are relaible but have all the personality of a wet carrot for the most part. You simply can't have it all.

I've decided to stick with it - buying a Disco is a risky stragtegy and at this point better the devil I know. I'm going to try retorquing the bolts and if that doesn't work then I'll out a new engine in. But I think I need to start diverting more funds into my rainy day account.
