oil overheating problem
I mentioned on here before I am having an oil overheating problem when the car is in MIVEC for extended amounts of time (highway crusing, for example)
normal temps are around 180-200f.. but in MIVEC this rises to 240f
what's my solution?
stay tuned..

my oil temps fried my bearings on myh turbo RA cause of cars high temps plus added turbo spooling in MIVEC. not good for crusing at 150 KMS for like 4 hours apparently lol
Oh well motors almost fully built now
PS they dun make undersize bearings for our cars yet so dont screw up your crank haha
Thanks

I still have about 90000 other parts i have to buy before i can put this on the car.
I am using a stewart warner gauge.. once i hit the onramp on the highway and start to whip it up to speed, you can see the needle slowly raise up to 220.. then 240..

*but then again, I'm sure you already knew that

i cruise at 80-85 when traveling and i never have this problem. have you had it checked out by the dealer? am i just missing something?
just for reference, whats the acceptable temp range for running oil? isnt synthetic made to run higher? IE: if 240-260 is hot, whats considered 'normal'? how much of a drop are we looking for?
also, how much does engine coolant have to do with oil temp? I figure most of the oil temp is caused by friction and not absorbing heat from the engine itself. but how much would new coolant help? waterwetter? what brand of coolant works well for high temp (summer in florida)? as the shop manual states:
Do not use alcohol or methanol anti-freeze or any engine coolants mixed with alcohol or methanol anti-freeze. The use of an improper anti-freeze can cause corrosion of the aluminum components.

Freddie1111, I have aftermarket oil temp and oil pressure gauges.. I am not using any stock gauges
importmonkey, where is your oil temp sender mounted? I mount mine at the oil filter location, which is probably the hottest part of the stream
to all, look at this http://www.perma-cool.com/Catalog/Cat_page02.html

Almost one third of the heat generated by the engine must be removed by the vehicle's two cooling systems. That's correct, your engine has two cooling systems. (1) The top of the engine: the area around each cylinder in the engine block, the combustion chamber areas in the cylinder heads and the intake manifold, dispel heat through the engine's radiator coolant system. (2) The rest of the engine: the crankshaft, bearings, camshaft, lifters, connecting rods and pistons are only cooled by engine oil.
The ideal operating range for engine oil is 180°F through 200°F. While operating within this range, the oil works as a lubricant, coolant, and cleansing agent in the engine. Modern engines generally run with radiator coolant temperatures between 200°F and 220°F with oil temperature ranges between 20°F and 75°F HOTTER. In other words, when the engine is performing flawlessly, the engine oil is already overheating! Oil that exceeds 220°F rapidly loses its ability to lubricate and cool causing accerlerated fatigue and premature component failure.
Perma-Cool® oil cooler coils are engineered for maximum cooling efficiency with no restriction in oil flow. Because different engines have varying oil flow requirements, Perma-Cool® rates Engine Oil Coolers by engine horsepower and oil flow rates. This results in cooler coil and engine flow rates that closely match.
Perma-Cool® Engine Oil Coolers can reduce the oil temperature to between 180°F to 200°F and keep it there. Benefits are:
Penguins
* Longer engine life
* Reduced heat load on engine and radiator
* Increased oil system capacity
* Lower under-hood temperatures and more!

I have an extra set of oil filter relocation kit for sale, pick up in toronto only, paid $90 CAD, will take $60 CAD for them.. new in box, never used.. I order them before I got my oil cooler and my oil cooler comes with their own relocation kit:

what does running the oil through a coolant system do to the oil pressure? its a restriction on the oil circulation, so does it increase the pressure of the system? if done poorly, could this cause the engine to sieze? kinda like adding a quart too much oil.... ?

lowering temperature = lowering pressure
silly puddy...i don't have any gauges. but i will probably be installing a few in a month or two when i start tracking.
yeah, i'll be putting one of these in shortly.

yes, lower temp = lower pressure as a general rule of thumb, but more restriction = higher pressure. dropping the temp 20 degress will barely effect the pressure. puting the oil thorugh 20 turns in a radiator could raise the pressure significantly. they changes are not proportional and prob wont cancle out. in other words, the system as a whole will probably see a pressure increase.
