Martin, Many thanks for your replies/info. When I add up the engine cost, the transport cost and the cost of getting the head skimmed including the risk, a remanufactured/reconditioned head makes better economic sense. I hope to tackle as a winter project.

Martin. Many thanks for your detailed and informative balanced response. I understand there is a risk of possible cracks in your engine/head. From the video, it looks to me like the blow by is probably coming from a push rod opening, and that the cylinder head gasket is probably gone between a...

Martin, Thanks for your response. Yes, I am interested but am located in Ireland and would prefer to find something closer to me. My main interest is the cylinder head, to replace a cracked head. Message me with the asking price and I will explore the transport costs.

Do you still have the 12J engine ?

The summary above is confirmed. New lift pump fitted and engine running again. I had a lot of difficulty bleeding the injection pump, but eventually got the air out after changing a few fuel lines and opening the pipe going back to filter while cranking. Will fine tune the timing this afternoon...

I am still awaiting the replacement lift pump, but in the mean time, through brainstorming on-line, and further reading, I think I have figured out the answer to my original question. The 12J timing is based on exhaust peak (EP). A Land Rover service bulletin for Series 1, that I saw online...

The fuel lift pump was faulty and I have ordered a replacement. I guess it was weak, but working, until I disturbed the injector pump. It was unable to lift the fuel when restarted. Replacement expected tomorrow. In relation to timing, yes, I mean the relative position of the crank to the...

Thanks tottot, My 12J is an ex MOD reconditioned engine. I have the engine for about 18 years and overall it has performed well. I recently replaced the cylinder head gasket after an overheating incident and afterwards it was not running well and was more smokey than usual. I suspected a fuel...

I am based in Ireland and have a 1985 90 with 2.5NA engine 12J. I am putting the engine back together following a problematic timing belt change (threads damaged on some studs). During the process the crank was accidently moved and I am now unsure about the timing marks. I want to ensure that...
