Thread: This might be expensive

DOHC diesel eh... You would have to guess them purdy valves would be laying over at just the right angle that when they got introduced to mr piston there was not a happy ending

As you say though - a good spanner twirling experience!

You know we will need photos of the carnage !!!

EAN ,don't forget the pictures,

yes they have the same engine as a Ranger, except the Ranger if its the 3.2 is the 5 cylinder version that you cant buy in a Defender, but same timing belt setup

In the last few months travelling we have seen both Ranger and BT50 (same engine) with similar problems, waiting for parts from overseas

this is one of the reasons I wont be buying a new Defender,

Just depends on whether it's an interference or non interference design.

Its a 3.0 4cyl but am told the defender has a smaller stroke, but is same engine.

Will be interested to see what the damage is.

They are Not the same engine as the defender , the Puma engine has chain driven camshafts for a start. The Puma 2.4 will be a bit more reliable in that department I reckon...I have just finished rebuilding one and they are quite a simple engine. Nice cylinder head and valve gear design, good looking porting etc and a very simple engine to time and reassemble. A fair bit of stuff hanging off them though, took nearly as long to get it ready for final install as it did to reassemble the long engine

I thought all diesels are interference fit, otherwise not enough compression for the bang.

The next car I'm seriously contemplating buying happens to have dohc 3 liter diesel, via camchain (not belt) with rockers designed to break in the event of a timing failure, so no bent valves or holed pistons.

I had a timing failure on a Toyota 1HDT which resulted in bent valves AND holed pistons, which is why the topic intrests me.

Hi Ean,

JC is right, the 3.0 litre in the previous generation Ranger is a Mazda unit and not related at all to the 2.2/2.4/3.2 Puma engines in the Defender and current model Rangers.
I'll see if there's any workshop manual stuff for these engines knocking around at work if that'll be any use to you?
