89 Supra

trdsupra89 · 04-30-2009, 06:44 AM

Hey guys, and gals.

Im new to this forum and to supras as well. Im 18 yrs old, and by no means a mechanic, but do know a thing or two. My last car was a 87 Toyota n/a MR2 and I loved the thing to death. When a dreaded rod knock showed up I had to get rid of her. I missed having it so I decided to look around for a new car as a project. I have always loved the supras, so I thought i give it a try.

I came across one, and picked it up for $600. just a few weeks ago. The owner said he believed it has a bhg...wonderful. (its a project tho right? haha)

Now I have looked all up and down this forum, in and out. Top and bottom.
Have read all 20 pages of IHATEHACKS bhg thread, excellent btw haha. So i figure if myself or my buddys cannot figure out what is the deal with this supra. Im sure you guys can.

Now onto the fun part.

When I first got her home.

There was glass everywhere from the neighborhood kids smashing out all the windows but one.
And whom ever tried to do anything with the motor did not know what he or she was doing because the wiring is a hack job. Im going to have to be doing a lot of splicing, and the O2 sensor in the turbo is not basically hanging by a thread...

Here is what I have done so far since getting it:
Tune up. New oil, plugs, ect.
Changed a lot of the vacuum lines due to them being hard as a rock.
There was oil in the valley, so I removed the 4 drain plugs, scraped the (Cyl #3 ) gasket/cover, and went out and got some oil drain gaskets, so I hope that fixes that problem.
When I did the oil change, the oil was milky...
But there is no smoke on start up, or all for that matter.

I know when there is milky oil and smoke it is usually a bhg, but is there any other reasons for milky oil besides a bhg?

I know Im throwing a lot at you guys right off the bat haha, but I have been meaning to post a thread here for a few days now, but didn't have the time due to being in the garage with greasy hands pretty much 24/7 haha

Milky oil is the result of water getting into it. You can run a block test on it to verify, but it looks to me like a typical 7M bhg. So I'd be very careful about running that engine until that's fixed or you're going to end up trashing the rod bearings (at least).

Oh, and I'd look around for a non- or at least less-hacked up engine harness. If the one you have is as bad as what you say, you're likely to end up spending a LOT of time chasing down bad connections, no connections, and a whole host of error codes.
