First, if the engine won't hold itself without putting the transfer case in 4L, you might want to run a compression check...with the "low compression" engine in my truck, it'll hold just fine in 2H in 1st or Reverse. I admit that I'll put the transfer case in 4L on a hill, but it's done as a precaution, not because it's necessary. I also religiously use my parking brake and would strongly recommend the same to anyone else, PARTICULARLY with a manual transmission.So far mine has held 15PSI everyday with just headbolts, its the low compression engine, and if i park on a hill i have to put it in 4lo cause the engine wont hold itself![]()

Second, is this the same truck you wrote "is getting worn out" about in your profile? ...in any event, I'd need to see an engine handling that kinda PSI on a regular basis for 50 to 75K miles with no issues before I'd be able to believe that doing so is actually safe for a stock engine. Not saying that the conventional wisdom on this (or any other matter) is infallible, but I tend to believe that that conventional wisdom was developed for a reason..which in turn leads me to contend that it will take quite a bit of empirical evidence to change that point of view (which, frankly, I have yet to see).
I will say for the record that I don't think I'd have a problem with 15 psi on my engine on an infrequent basis (11 to 12 is probably better on a regular basis), but I'm also running studs and relatively new head gaskets...
Sorry for the OT post; just had to get that out there...
yes yes i know the engine is completely worn out, and there is no reason for me to do a compression test, all its going to do is tell me what i already know, i know it needs rebuilt, but i dont have the money to do it,Fair enough. With that said, I think you would be doing the IDI community as a whole a big favor by reminding people of this fact every time you talk about the way you run your truck. You have a right to do as you please with your equipment, and I respect that (although I'm also sad to see what should be a good truck/engine being abused in such a manner)...but, my single biggest fear is that someday, someone will do a search and find your posts and, without researching further, will assume that what you're doing is "normal" and safe and inadvertently destroy a perfectly good engine.Yes i know the safe limit on an idi is much lower than what im running, and i dont recomend anyone running there engine like i run mine, but it sure is fun![]()
but had to give my $.02...
