IM4LC38 Head gasket replacement

[stevenjoanne]

I am about to attempt a head gasket replacement on my Isuzu 38 to say I’m nervous is an understatement, however it’s got to be done ……

has anyone experience of this engine and complete the same gasket change .

 

also can anyone point me in the right direction of a workshop manual for this engine .

 

many thanks

Are you sure about it being an IM4LC38?

 

There is an Isuzu workshop manual here:-

Does that help?

Identify the position of the failure and eliminate any cracks in head or block. Buy a genuine Isuzu gasket. Check the flatness of the cylinder head and block with a straight edge. Make sure the head and block are perfectly clean(use a plastic scraper) and the bolt holes are clean. Do not use any form of sealant. Check for any stretch in the head bolts.  Use an angle gauge to set the stretch on the head bolts when re assembling. Ensure correct orientation of gasket. Determine the cause of the gasket failure(overheating?) to avoid a recurrence.

Hope this helps
