S40 Engine B4204T3 Blue smoke when idle

Post by jumbicat » Sun Sep 02, 2018 9:21 am

I had 500' of welding leads in the trunk and suspect too much weight caused the problem.

When entering the highway on a uphill grade, the transmission kicked in the passing gear and believe something happened at that time. Shortly after started to see smoke from tail pipe.
Being careful on what additives are being used to test. At this point, I've only use oil additives to try and stop the smoke. Nothing seems to be working. I don't want to do the water additives due to possibly causing more damage. I use YouTube to validate, not get my information like most do these days. I'm ready to start a head gasket kit repair but wanted to get some feedback from the experts Don't want to create un-nessary work. I can't help think it's a simple fix.

139K miles
No water in oil.
Runs good just smokes.
Glove test on PVC seems ok.

Should the water treatment be considered?

Thanks in advance for any thoughts,

Mark

I'll do a compression test soon as time permits. The engine runs fine, just blows a ton of smoke.

If you have driven for a while very easy and then did a high load, higher boost drive you might have nothing more than displaced accumulated oil that was sitting in intercooler and now has puddled in intake manifold and is being consumed. If you drive aggressively regularly then never mind....

If the first scenario fits then look in hose to throttle from intercooler and hose from turbo to intercooler and see if there is a wet oily film

The S40 was driven daily. Until the mishap on the on ramp.
Thanks for the response,

Mark

How much does "500' of welding leads" weigh?

When entering the highway on a uphill grade, the transmission kicked in the passing gear and believe something happened at that time.

Can you be more specific? Just downshifting a gear or two wouldn't concern me. Did the engine go well beyond redline?

Shortly after started to see smoke from tail pipe.

Under what conditions was it smoking from the tail pipe? Under load, while coasting, when pulling away from a stop, when going up/down hill, etc?


Being careful on what additives are being used to test. At this point, I've only use oil additives to try and stop the smoke. Nothing seems to be working.

What additives are you adding? How many miles or cycles has the engine been run with said oil additives

I don't want to do the water additives due to possibly causing more damage.
I don't know what "water additives" you're considering and/or why they may do more damage.

Should the water treatment be considered?
What "water treatment"?
Not trying to bust nuts, just trying to get more info.

1000 or more lbs.
Possible it did red line RPM, but acted like a down shift and extra weight could have put too much of a load on the engine.
Smokes in all described scenario questions.
One of the products was Rislone Ring seal smoke repair.
Water additive to seal open gaskets.


Compression test hopefully will provide light on issue. My concern is if the piston o-rings are shot, it's not worth fixing and should sell as salvage. Kelly's Blue book says it's only worth $1400. But wife says since it's paid for it would be worth investing in. It's just taking up space in driveway. Took it off insurance since we have 3 other cars.

Hope everyone is having an enjoyable Labor Day.

Wet/Dry Compression test results:
Dry 145-149=150-145
Wet 15-48-30-79

I understand doing a wet test is supposed to increase pressure.

Huh?
Yea, something doesn't look right with those readings. The dry numbers are "eh ok", and I'd think that the engine wouldn't smoke.
The wet numbers are just bizarre.
I wonder if something got caught in the compression tester. Just seems really weird.

Did you get a chance to pull the intercooler hose and check for oily residue as suggested earlier?
I don't think 1000# of cargo and redlining the engine is enough to destroy a whiteblock. Maybe the rear (suspension) springs, but not the engine...ha ha.

Did this car ever overheat?
At first I was thinking possible valve seals. But I think by 2003 Volvo had that issue solved. And worn valve seals usually showed up as blue smoke after 4-5 minutes of idling - not when just driving along.

Got a loaner tester from local auto supply shop.

May need to buy one just to have and to confirm readings. It's possible, too much oil was added to the wet test and was pumped up into gauge. I should call the store and let them know.

No, I have not checked the intercooler because it was stated if the car was sitting up oil may have pooled. Since it wasn't, didn't seem pertinent. I'll check regardless.

In looking for things to try, I ran across a you tube poster that pulled the head thinking it was the head gasket only to find it was the radiator causing oil to mix with antifreeze. I respect the fact he still posted the video but goes to show not everything found on the tube is the correct way to troubleshoot.

This is very strange. The engine runs fine, just pumps out a lot of smoke. Antifreeze looks normal, oil looks normal. I was thinking about draining oil and run Marvels Mystery oil to clean out engine. It's possible its as simple as a clogged tube or hose?
