Holden Inj V8, into P38

**Pierre** · 25th January 2007, 06:49 AM

I've just done it to a 4L block (55D) from 99 Disco 2.

The liners are a stepped liner and are inserted after the block has a step amchined into the decks.

This solution prevents the liner slipping and guarantees a seal around the fire ring on the head gasket. Unless there is a catastrophic coolant loss which goes unnoticed, the engine doesn't leak coolant leading to overheat failure.

I got the liners from UK, had the machining done in Melbourne.

I am a happy camper!

The procedure is outlined in Des Hammill's book - "How to Power Tune
Rover V8 Engines".

Cheers

Actually, the price I was given was very good. I won't say in case it was mate's rates (not to me).

G'day Folks

Top Hat Liners are also known as Stepped Liners

they are common in diesels, the liner has a collar around the top, the block has a recess machined into it, the liner is then pressed into the block, seating into the recess, this insures that there is a gas tight seal around the head/block join

that then eliminates the slipped liner problem. the main reason that stepped liners were not used would have been production cost

"Sells Spare Parts"

these liners should be available in Australia,as they would be a standard production size, they are usually sold by height, diameter, length, and grade.

Pete........

How much did it cost for the liners and to get the machine work done?

I have the book as well and am looking to build up a reaonable quick motor. Fair amount of info to sort through though.

I'd also be interested. I've got my old 4.6 block sitting in the garage.
