87 supra using oil.

[Rob1]

I actually dont see any smoke coming from exhaust and today i realized that i think it is leaking out somewhere but hitting something hot before it can hit the ground which would explain why i dont see any on the ground because when i get out of the car i can destinctly smell burnung oil i thought it was my power steering cuz i had a leak in it but i took my ps belt off and i still smell it shortly after parking. is there any place you have seen it leak from that that could happen?? can oil leak from head gasket without mixing with coolent or getting into cylinders?? im at a loss:/

Was there synthetic oil in the car before you put some in there? Synthetic oil is thinner than conventional oil and can slip past seals till they get used to the oil. I haven't put synthetic oil in my supra for partly this reason, other reason is I pref. high mileage oil since I'm getting close to 140k miles.. However, I have seen this first hand w/ my stepfather's Buick Grand National when he went from conventional to AMS Oil synthetic... the next morning the car had dropped most the oil from all the seals..

Check under the distributor for any oil on the exhaust manifold heat shield, a very common problem is the distributor O-ring needs replacing. Probably won’t account for the oil usage but defiantly will produce a strong oily smell under the hood. Unusual for the head gasket to leak around the oil path, they are some distance away from the combustion chamber and coolant gallery’s, I doubt if it’s the head gasket. If there is no evidence of a leak then you could assume its burning oil due to piston rings or valve oil seals, not uncommon on a high mileage engine, just check the oil frequently. Oh! and I agree with Krem synthetic oil is not recommended in the UK, most owners use semi- synthetic.

well i am only running synthetic blend not full synthetic

[Rob1]

would you recomend just running conventional?? and the

I used Duckhams for many years in my first Supra in 1986.5 managed to do over 250,000 miles with no engine repairs apart from the odd BHG and a few puffs of smoke on de-acceleration now and again (you would expect a little burnt oil with 250 K) I've had two Supras since then, the current one being a 90 Turbo. Duckhams although still available over the Internet and a few small auotoshops isn't an oil that you hear mention now days. Come to think of it; I'm not sure why I changed to Castrol Magnatec 15- 40 part synthetic I think the lack of availability and probably the recommendation by other supra owners to use part synthetic.

yeah im running the 10w30 synthetic blend part synyhetic you think i could be burning it up slowly cuz its to thin oil??
