Help Removing Oil Pan, Please - 96 GP3100

I would recomend pulling the block so that it can be cleaned better. I suggest taking it to a engine shop to have it hot tanked. Then all your oil passages will be clean, cam bearings can be installed. With out any slug in the engine your oil will stay clean longer. In the end you will have a better engine.

In a perfect world that would be best.

But in best opinion, the engine is only about 60k miles and I routinely changed oil/filter and used Seafoam treatments every so often. In short, I shouldn't have much if any build up in the passages. Since then my oil stays a nice golden brown for a good while.

So I am going to pass on the hot tank. When I hone the cylinder walls there will be a good kerosene flush following.

The block exterior is already really clean. I spent a long day crawling around the block with heavy degreaser, a tooth brush and a water hose to rinse (long day). That was a few months ago during the beginning of my turbo build.

In short, the engine is in great condition already. But the damn valve seat falling out and pounding piston#6 makes me question the rod bearings, wrist pin and main bearings.

So it is more or less an opportunity to replace pistons/rings for stronger and replace bearings and wrist pin just in case the impacting damaged them. I already have the replacement head mildly ported to match the other. I'm pretty sure the wrist pin is strong enough to handle the abuse it took but the bearings worry me.

And by all means, I am not trying to 'know more' then what I am told. I know hot tanking the block and having it pro-bored/honed would be best, but budget is a little tight after having to purchase a new head, piston set, moly rings, rod bearings, main bearings, ridge reamer, ring compressor, assembly lube, gaskets, ect.... It really adds up big time. Especially if I decide to go forged pistons.



What I really need to know is how to remove the Oil Pan Bolts that are hard to get too.
