I checked my coolant and the color is a brownish and I am certain there has got to be engine oil in there. what causes this and how can i fix it?
Engine oil mixed with coolant...
- Thread starter JDMSupra
- Start date
how long has it been since the colant was changed, and the system flushed? May just be old coolant (kinda dirty), or maybe a previous owner mixed different color coolants (not flushing when switching from red to green)
Try flushing it out, and see what happens.:dunno:
Hopefully there is no oil in it, or it could mean :icon_evil: BHG !! Oh no!!

that is what i was thinking... i also hear the infamous "gurgling" noises from the engine/dash area... if i do have a BHG is there a chance i have ruined anything?
hmmm, depends, is there any coolant in the oil, coolant disappearing?
I would do a compression test, or maybe a block test, and if it comes back positive, don't drive the supra any more, park it now.

i just bought the car and this is the first time i have looked at the coolant reservoir but there is very little coolant left. how would i go about doing a compression test or a block test?
First, flush the cooling system.
Second, the block test is a kit that you can rent from, say, Autozone or Kragen that sits on top of the radiator, and detects any exhaust gasses in the coolant, which would mean=BHG. This is definitely the easiest way to do it, but won't always tell you if you have a BHG, when I had my BHG, it didn't detect anything, and I didn't have the gurgling noises behind the dash.
The Compression/Leakdown test is probably best performed by a shop, if you are a noob but it basically involes pressurizing each cylinder through the spark plug hole, and measuring how much pressure each one will hold, greatky varying compression #'s will indicate eaither BHG or worn rings, but usually BHG. This test is definitely the most accurate method of BHG detection. Hope I helped.

I just did a compression test on my mk2. I got the guage from a local motor factors for like £12.00. Real easy to do. BTW it passed so i must have worn out rad.

supramad77-DAMN! ^^That mk2 is BEAUTIFUL!! I'm not a mk2 person, but that has got to be the best looking one i have seen to date (maybe it's just because I love white :biglaugh
Nice Job!!
Nice Job!!after having my car parked for 3 and a half months i found the dark brownish crap in myt coolant res too.. im a little scared.
