Head Gasket/ or cylinder head crack has recently caused Coolant seeping into combustion chamber & existing exhaust. I read all the posts I can find to get info on the challenges of engine replacement & replacing Cylinder Head in van. If I do a JDM engine replacement cost isn't significantly different then having Head rebuilt or replaced if not repairable. Van has 240K miles, but always keep maintenance up.
From those with experience in doing either method, would you say replacing cylinder Head in Van can be more challenging do to access to remove the Intake? Would you say engine replacement is easier if you have a good method of lowering & raising engine? The two main methods shown on this forum- lowering from top or lowering from below seem to both have advantages/disadvantages,
I've done quit a few engine rebuilds with Twin Cam engines, so a conventional engine or cylinder head replacement isn't a problem. I also have the Toyota workshop manual for more reference.
Any recommendations?
