      Since we built the 1970 455 HO engine for my blue car, it has had cronic high pressure oil leaks on and off.

      First, the leak was from the oil sending unit... fixed.
      Second, we found a hair line crack in the oil filter bracket...fixed.

      Now, we have determined that the leak is coming from the oil pan gasket on the passenger side rear corner area. We reinforced the old oil pan bolt holes with a custom made stainless steel plate much like the shorter ones found on your valve cover bolts, but since the crackshaft main bolts spin slightly in the oil reserves, it is still leaking. My builder says that he will order a deep sump, Nunsi? oil pan to prevent the crankshaft from spinning in the actual oil reserves and this should fix the problem. I have reminded him constantly to get the piece ordered but he has delayed, delayed until now, we only have a month left to install and have some time to drive the car and test the new pan for leaks. eek image Hopefully, he will have the pan and I can get it installed before next weekend's run to Tifton for the Tiftarea Auto Club Cruise in and Car show. There we will be finalizing the plans for the arrival of the Bandit Run on May 16th! cool image

      At the present time, that"s what is going on under my hood! How about yours?

      Got all my suspension taken care of with the new stuff. I started redoing my nitrous system. Pulling out the mechanical nitrous pressure gauge on the pillar for an electrical. Well, while pulling the 16' of -4 nitrous line out I've somehow cut power to the lights for the gauges on the pillar. So some night this week I've got to run some wires and find my break, fix it and then run the wires for the new gauge.

      Put new plugs in on Monday. Not that hard to do except for the back to on the passanger side. Fighting for room with A/C and the engine sits back under the cowl. Had to get the back cylinder from under the car. It's done and marked off the "TO DO" list.

      I've got some new braided brake lines for the car. Just haven't decided if it's worth the headache to change them out and bleed the whole system with ABS.

      And lastly, Final tune on the 19th of this month. Get everything spot on for the run and upgrades. Running really rich right now. Should help with gas comsumption!
       

       

      How's this thing go back together???

      on my turbo 301, had to sleeve the block today, 2 cylinders slighty out of round, and to bore it would mean, I have to seek out ross custom made pistons to the tune of around 800 bucks so sleeving is the other option, crankshaft polished out great, #4 journel, slighty out of specs for stock bearings, but should be fine as they all seat in.......new KYB shocks,installed all urenthane bushings in the rear leaf springs and front upper control arms,both upper and lower ball joints replaced, replaced all rubber fuel lines,replacing body/ frame bushingsthis weekend,also replaced both u joints,transmission front pump seal, and rear trans seal and bushings, tires all mounted on 8 inch turbo rims instead of the 7 inchers that were on the car..rebuilding the carb also this weekend, the headliner and cb will be installed at the end of the month...the engine is the most important thing right now, ..have to order a few parts from the "301 store" for the turbocharger, otherwise, should be ok...may install new straight threw mufflers also.depends on time....have to get a rear axle to C-ya in NC, as they told me there rear end is geared high, and that the engine is in the 3000 range at 70mph.and they need a space saver spare, so I told them I would bring them the rear out of my brown T/A, its a 308, just not posi...so thats whats going on in my Garage, or driveway....

      I LOVE MY TRANS AMS........cant wait to drive it like I stole it biggrin image ..by the way, just on your oil leak, is it only below the heads?, like rear main, oil pan gasket, front seal, and which oil pump are you running, melling, makes 2 pontiac oil pumps, a high pressure(M54D-S) 62psi and a SD/HO (M-54F)at 80-82 psi, this pump will do what you are describing if your not running the crankcase vent/pcv set up,the factory had on these engines,via, pcv thru the carb base, and the breathers on both valve covers to the aircleaner tub, if your "venting" the rocker covers, this may be the problem, had seen this on another pontiac motor,and a non SD/HO block cannot handle the added pressure, a tech at melling just recently told me this when I called to see if a oil pump for my turbo motor still existed(heck no.)he said DO NOT run the 54F pump in either the 301 or any non SD/HO pontiac block.that being said, you stated you have a HO block...is that correct?.and have you hooked up a manual oil pressure gauge, tapped it to the windshield and drove around to see the oil pressure during "real time: driving?just trying to help narrow down your problem, the more we all add our 2cents one of us will nail it........."East bound and down eighteen wheels a rolling, we gonna do what they say cant be done".............................RIP JR
