on my 2.2 turbo2 auto oil pressure gage starts out fine and read's fine after about 10 minutes gage drops when idleing or shows low pressurs unless on highway any idea's anyone all my other tc's are 3.0S i am gessing oil sending gage or bad oil pump don't know location of either. any idea's thank you

start by cleaning and dieletric greasing hte connections to the sender. then replace sender. none of that works, could be pump going bad or bad main bearings

The 'book' says the 2.2's only need 12PSI oil pressure at idle to stay happy, I don't think the idiot light comes on til 8 Cleaning/checking connections like 16V suggested may fix the problem, plus the sendors do go bad especially if there is oil seepage at the wire end of the unit.

If those fail, run thicker oil or a bottle of Lucas with each change. Ya gotta pull the oil pan to replace an oil pump. Not too tough but not exactly an easy job if you haven't done one.

Mike , Touching on what Alan said, I run 4 quarts of Mobil Delvac 1300 15W-40 oil in my engine along with 1 pint of STP. Heavier weight oil is not just what you are looking for but one that is also formulated for turbocharged engines. 15W-40 is suggested in the owners manual as a choice of oil. Check the temperature ranges to see if it is applicable for you. Good luck, David

15W-40? thats the choice of oil recommended for Turbo Diesel trucks, i highly doubt a 2.2L Turbo, all mine have said 5w-30 or 10w-30

Hey Guys be very very carefull how heavy (thick) the oil is that you run in a turbo. That turbo turns up 20,000+ RPM and the shaft bushings have a clearance of only .0015 when up to temperature.. My choice is always 10/30 Mobil 1. Lou

I guess now is not the time to say I ran Castrol Synthetic 20w50 in my old LeBaron Turbo I for 230,000 miles on the original engine and turbo...

<ducking and running>

where is the oil pressure sending unit located on car do not have manual on 2.2 thanks everyone will use heavier oil after finding sending unit and testing

OK Steph.....

Look a few inches below and to the right of the upper radiator hose coming from the cylinder head. See the little fitting protruding from the engine block, it has a small silver hardline oil line that goes up then over along the drivers side of the cylinder head? That is the oil feed for the turbo. the sender is also on that fitting. 89 may be silver 'bell'shaped or black and the size of a roll of quarters depending on your build date. It has one or two wires going to it. Bingo, sender.

Alan

twin cam, if you still have your owners manual, look in it. 15W-40 is recommended as a choice and as you are correct about it being for diesel engines, I run it in my Dodge's and my Kenworth's. 15W-40 is also recommended for gasoline turbocharged engines.

The temperature zones for 15W-40 are from 10 to 100+ degrees .This information can be found in the lubrication section of the 89' service manual in section 0-6 .

The manual also highly recommends not to run 5W-30 in a turbocharged engines in temperatures above 60 degrees. Twin cam , you may want to drain the 5W-30 for your summertime pleasure if it is your engine now.

Ya gots me mixed up with that other guy David, I am all about the thicker oil. It was some other know-it-all that threatend the heavier oil would tear up our turbos or some othersuch malarky. I just left that one alone, you never can change a know-it-all's mind anyway

Alan

Alan, sorry for the mix up. It was 89TC-16V. I have had lots of experience with turbocharged engines, not counting the itsi bitsi one in my TC that could be used for a starter motor. I even ran 15W-40 in some race engines we built back during my round track days. Never have I had an oil related engine failure.

i run 10W-30 synthetic in all my turbos, thats 4-2.2Ls, of which one is a 408 whp, 442ft lb trq 16V monster. 15W-40 is way too heavy in my opinion to push through small oil passages and lines, maybe on a 3.0L, but never a 2.2L. why they have that in the 89s book is beyond me, i have the books for all my other cars they say 10W-30. i would think 15W-40 is a little heavy considering what chrysle has to say about the oil in the book

just for kicks pulled directly from my 89 owners manual page 83. SAE 5W-30 is the oil preferred for use in all engines within the operating temps show. you are highly encouraged to use SAE 5W-30 to aid in low temp starting and for improved vehicle fuel economy. SAE 10W-40 and 10W-50engine oils are not recommended for use on Chrysler motors vehicles. these should never be used in turbocharged engines

That's pretty much what I read from different manufacturers in the '60s. but of course we mostly ran single weight 10w, or 20w, real hot long runs 30w. At that time we also played with special hydrolic lifters on different hydrolic and solid lifter cams, running anywhere beween .002 & .004 clearance. we found at that time in almost all installations 20w Castrol gave us 400 more RPM before lifter pump-up, than any other oil.. Just another old timer rambling, Lou

I never said anything about 10W-40 or 10W-50. I said simply 15W-40. Can you atleast acknowledge I am not out of my mind. It is in the book. Further more I hope you do not believe just because it has a turbocharged diesel in it 15W-40 is the oil. Try that in an older Detroit and you will destroy it. SAE 30 is what you had best use, non detergent on top of that. You may believe 15W-40 is way too heavy for your torque monster and I say that tongue in cheek but it is more than sufficient to answer the original question. Perhaps we should just let the fella make up his own mind because you and I will never reach an end.

if 10W-40 and 10W-50 are not recommended, what makes you think 15W-40 is any better? its a good deal heavier, thats only going to make the oil pump work harder when the temps are lower, if you live in the desert, its probably fine, but the rest of the world running that in a turbo, you are gonna roast the turbo if the stuff cant pump to it before you start driving or the bearings unless you let the engine warm up for 10 min if its not 70+ outside. not to mention heavy oil in a turbo isnt much better for the main seal, ppl have blown them out of the block running it because they rather put heavy oil in than change the bad pump or main bearings. obviously its his choice what he wants to use, he can stick gear oil in it for all i care, i posted what the book says, does not say run 15W-40, its part of the chart for the Sahara, Gobi, Death Valley and certain parts of Iran, its says 5W-30 is the recommended oil, 15W-40 is not the next oil heavier in weight. This is a 2.2L 4cyl from the 80s, not a 50-70s V8, these cars dont have solid lifters, flat tappet cams, double roller timing chains or 4 barrel holley carbs. I've dealt with over 10 of these 2.2Ls over the past few years, i have yet to have any problems running 10W-30 in any of them, low mile, high mile, turbo fuel injected or Carbed.

Why don't you look at the image YOU posted a picture of? The chart that reads "Recommended viscosity grades"? Look at what is 2nd from the top.... 15w40

Your own data, dude.

Thank you Stephanie.

I know you may find it hard to believe being from the highly intellectual center of the country (NJ) but Virginia is not part of the Sahara not in California's Death Valley. Read the chart that you so proudly posted the picture of and tell me if the temperature ratings for 15W-40 do not range from +10 degrees to 100+ degrees. I know we are not as bright down here as ya'll are up there, but I can read a chart.

C'on guys and gals, we're discussing oil. Lets not get in a snit over it. We all can read the manual, and we all also know the manual is infallible! Right?
I personally wouldn't use anything heavier than 10W-30 and most often use 5W-30, but lets face it, if someone is comfortable using gear oil, what the hell! After all we all live in different parts of the continent and operate under dozens of conditions. Let's shake and makeup!

run what you will but dont expect a Jiffy Lube or anyplace else to put that in your car, they would get sued when it blows a seal or the turbo and when they look at the recommended oil, it doesn't say 15W-40

I would hardly use Jiffy Lube as an expert reference for ANYTHING to do with a car. You couldn't pay me to take my worst enemy's car there.



That is of course assuming the guy at JL can even read.

That being said, your own image shows very plainly that 15w40 is in fact a RECOMMENDED oil. That is the title of the chart, correct?
