What I am interested in - and probably other newbies that have not done a head gasket job on a multi - are tips for what to do and what not to do and how to do it, from people that have done this job.
I would like this to turn into a walk-through for the head gasket job. Seeing that you clicked on this thread, it is likely that you either need this info or that you can contribute.
The TM for multi engine repair speaks to the teardown and re-assembly process. As I know from many other jobs, there are different ways for getting the work done right. If you work in an armed forces garage overhauling an engine, with access to whatever tools you need and ample time on your hands, it may be worthwhile to disassemble everything, as per TM. Experienced mechanics here on SS may be able to tell first timers, how to do a good job without getting themselves into a mess.
Some things I throw out there:
- removing valve train, yes or no? Can I leave the guts of the head intact?
- someone removed heads with manifolds, turbo etc. left attached. Advisable?
- details on block surface prepping; scotchbrite pads a no-no?
- when using m35-tom's new style head gaskets, is there any additional coating (Permatex; if so, which one?) advisable? All around or just certain areas?
- head bolt wrench; I saw many home-made ingenious solutions and a suggestion to use a 7/8 sensor socket.
I collected threads that contain some information, many are really useful, but none is "THE" authoritative thread on doing this job. My theory is that if there are so many threads on one subject, none of them has all the needed info!
