Does anyone know if there is a freeze plug under oil pan 91 previa?
You get coolant in the oil most often from a bad head or bad head gasket.
Never saw a freeze plug inside an engine. You posted a similar question earlier. Head gasket or cracked head most likely.
I have been maintaining, and repairing, not only my own vehicles, but those of family and friends, since I bought that 64 Ford Galaxy XL back in 1973.Quote:

He replaced it and it ran good. I have replaced a few freeze plugs in my time, and I never seen one like it either. I think I believe the article, and am just wondering if my 91 is like that 93. I have tried Autozone.com, and called them on the phone, couldn't get any info. As to location of the freeze plugs. Toyota service dept. is closed today.
I really do appreciate you taking time to help me, thank you!
That is a very poor choice for a freeze plug. I have seen them under flywheels and bellhousings but inside? Never. Oil pan on FWD cars are usually fairly easy to remove since the pan runs crosswise. Probably worth a chance. I did look on Youtube and there is one in the 93. HMMM!
I think I will try it, Ill let you know what I find, thanks!
Well, I dropped that oil pan, and found not one, but four freeze plugs! Three were average size, and one was approx. one inch diameter. All were intact, so looks like I'm replacing head gasket! HMMM!Quote:

I might not waste the oil, I might scrap this van, high mileage, etc.,.Quote:

No. I do not work for Haynes. My son and I restore a lot of cars and repair a lot of older ones and have found those manuals give the best general information for most repairs.
