Thread: 350 N Deisel

Other than the injector pump probvlem, there shouldnt be any. The olds 350 diesel, block crank rods and pistons shouldnt ever let go, BBC isnt universal, its for those that want to give someone alot of money to recieve a fast car, none of the pride of doing it yourself, none of the pride of trying something new and succeding.
The 350 diesel has 3" mains and gas SBO rod journals.(strong)
A very easy change would be toswap the diesel hads and intake for old gas olds heads and intake, wont be quick, but itl run forever The diesel pistons and rods weigh a ton, but are as strong as strong can be.
Another option would be run it til it dies,(it will outlive you, plus the great mileage and low fuel costs) and replace it with a direct bolt in SB or BB olds. I had a 81 supreme diesel, replaced it with a 461, bolt in and go. \

Another option would be to keep the diesel block, Olds 425 forged crank with counterweights cut 3/8 inch and SBC rods (stroked or destroked crank, and custom or off the shelf chevy pistons with some killer heads and go fast forever, no need to worry about a soft block(it isnt chevy, its olds, so no toothpaste blocks) Email me for more info< please no Olds hate mail or chevy rules mail

I'm @ a total loss now.

i own 2 olds diesels and they both get 25 mpg and have over 200,000. The first diesel that came out had problems but in 1984 they had all the problems worked out but the injection pump diapham. If the diersel you are buying is running i'll bet its been replaced.I have had both diesel cars since about 45,000 and they have been great cars for me. Both of them start good and have plenty of power for diesels.

I would pull the injectors and do a pattern, leak-down, drip, and popping pressure test. Faulty injectors were a cause of a lot of the problems associated with early automotive diesels, cracked heads and broken pistons. If you're crazy, you can make your own test stand using a hand operated hydraulic pump and a 3000-5000 psi guage depending on the popping pressure. If you have a faulty injector, they are generally not difficult to service. Especially if they aren't unit injectors. The most difficult part of rebuilding injectors is mainting an extremely clean environment. Injectors use no gaskets to seal internal parts, all parts are lapped together to create tolerances so tight that 5000 psi diesel cannot leak through them. Any small piece of dirt or corrosion from finger prints could cause an injector to leak-down excessivly.
