looking to flush engine.

[dlmrun2002]

Any ideas on how to rid my engine of lots of gunk inside? Engine came that way but I would like to flush it out if possible without blowing it up. Oil has been changed regularyl. I heard adding a quart of ATF for about 50 miles before oil change will clean it up a bit... Any tips?
Thanks..

tips, change your oil regularly as well as your filter.

Seafoam?

I've changed oil regularly. •••••Previous owner of engine didn't change it I assume.

ATF will clean it out some due to its high detergent content. But don't run it for too long.

Lubro-Moly makes an engine flush product. I've used it before, you just run your car up to operating temp. add the bottle, idle for like 10 minutes, then change your oil. I don't know how well it works but the placebo effect is good in any case and I do trust lubro-moly products.

Change your oil weekly for a little while until new oil put in is clean looking on the dipstick.

all the old timers that hang out in NAPA all saturday morning drinking coffee and talking rebuilds swear by seafoam.
For what its worth.

just seafoam it once a year (in the oil) if you are bad with your oil changes. otherwise just do it once so you have a clean slate and keep up on the oil changes.

lots of people run regular oil, i run mobil 1 15-50 and go a little longer on the oil changes. when i first got the car it ran conventional oil and i did 2 short change intervals with the mobil1 and got some pretty dirty oil out.
i added seafoam at the next oil change and got some really nasty crap out of it.

after that, the oil was much cleaner in between changes. i just did it again 3 months ago (3 years from the last time i did it. there really wasn't much gunk compared to the regular oil changes.

like he said. seafoam has been around for a long time. just youtube "seamfoam DIY" or something i think theres even a couple e30's on there. 1/3 in your gas 1/3 in you oil 1/3 in your intake.
im about to do it to mine

that sounds pretty expensive

Have you ever pulled off the valve cover?

Notice that odd looking tube that runs across the top of your motor, over the cam? Notice the several little holes along the bottom. They squirt oil.

That lubricates the little shoe that rides the cam...that little show has LOTS of pressure on it.

If that tube gets clogged, cam gets no lubrication...causes this horrible cam wear:



Moral of the story is do something about that spray bar. Clean that bitch a couple of times after you do ATF or Lubro-Moly or (my choice) Marvel Mystery Oil.

Then after you can keep the oil clean for 800 miles or so, replace it.

Well, we wouldn't want to have to spend any actual money on our cars to have them running correctly and reliably, now would we?



If you want a car you don't have to spend any money on or pay attention to, go buy a Honda.

Leave the E30s for the guys that actually want to spend the money and do the upkeep to have them run well.

Hondas are awesome.

[Jand3rson]

Some of them are, yes.
