It's been awhile since my last update. Finally got some some off work, and since I don't have a garage ready to do any extensive work yet, I figured why not have a look at the pickup screen.
I drained the oil, and used a Q bit and drilled a hole under the center of the screen. Sure enough the screen was pretty much plugged. I spent about an 30-40 minutes with a can of Berrymans B12 spray and an assortment of metal picks, and got the screen good and clean.
I tapped the hole with a 3/8-24 tap, and put a bolt in it using a rubber washer, with a metal washer of the same diameter on top and tightened it down. and had no leaks.
I started the truck, and had around 80psi on startup, and gradually went down as the engine warmed up. The pressure stayed around 10psi or a bit over at idle for 20 or so minutes, and roughly 60psi at 2k. I let it idle another 5-10 minutes while I cleaned up my tools, and when I rechecked it, the pressure was still at or just above 10psi, and about 30psi at 2k.
At this point I decided to take the truck to the gas station 3-4 blocks away. Did good right up until the turn to the station, where the pressure dropped to 0. I got the truck home, and hung my head in defeat with a few choice words.
I was sitting inside and I suddenly thought to myself, what if the screen is plugged again? I figured probably not that quickly, but with my newly installed plug, it was easy to check. I started the truck, and let it run until the engine warmed up, noticing that the pressure wasn't as good as earlier. Only about 30psi, and after dropping closer to 10psi, giving it some gas didn't raise the pressure much like before.
I drained the oil and had a look with my endoscope camera, and sure enough, the screen was mostly plugged again. Had a look around the inside of the pan and there is still areas with allot of deposits that appear to be somewhat loose. I figured that could be why the pressure holds so good until it's driven, and the oil starts getting sloshed around, freeing up those loose chunks to be sucked up into the pickup screen.
I haven't dismissed the chance that I may still have to take on the task of dropping the pan, but I must say this gives me a glimmer of hope. Last time I used 96oz can of chem-dip. I plan on putting 2 cans in the pan this time and letting it soak for awhile in order to clean more of the pan out, followed by flushing the pan with a few gallons of diesel, putting in 6qt of oil and 1qt of atf, and letting it idle for 10-15 minutes, followed by draining and flushing the pan one more time before refilling with fresh oil.
