so Hey! Whats up mate? thank you for your time reading this topic. its really appreciated.
here im gonna post all my questions for any particular behavior my engine has or will have eventually... :yes:
the engine smokes a lot, through the muffler and through the turbo zone.
i have read that it can be either:
1-. a blown head gasket
2-. Faulty pcv valve
3-. Faulty Turbo.
is there an easy way to trouble shoot each?
id like to avoid having to tear my engine open just to find out it was the pcv.
Check the turbo for shaft play, does it smoke when you come into boost or just all the time
What color smoke? That will point you in the right direction.
Does anyone know how to wire our analog clusters to work with the SR?
No idea about the wiring, get an oscilloscope and check what kind of signals you have. Then you can convert them with simple/cheap electronic components.
Did you solve your smoke problem ?
For the pcv, just remove it from the valve cover and check again, if there's a lot of stream, this is not good for you.
I'd say it can come from the turbo, it's the most common fault that turbocharged engines have. Check the lowest point in your piping (often near the intercooler) for oil.
If the intercooler/pipes have oil in it, then your turbo is toasted, if it's not too late, you can maybe rebuild it ...
Also check your oil feed and drain pipes on the turbo, they may be leaking.
If you want to check for blown head gasket, remove your spark plugs and apply pressure into your cooling system (an old radiator cap drilled out and completed with a tire valve work great) never apply more than 1 bar pressure, as your expansion tank may explode. Leave it for half an hour. If the pressure has dropped more than 10%, there's a leak, if you don't see it, it may be inside your engine. Try to crank it w/o the spark plugs, doing so will remove any water that could have gone into the cylinders. If water comes out, no doubt your head gasket is blown.
Also check how your oil looks. It should be black/brown, liquid and without lumps.
If you have yellow lumps or something that looks like mayonnaise, it means that there's water/coolant in your oil, so your head gasket may be blown as well.
If all of the above is okay, then do a compression test, you should have around 10 bar for each cylinder. If you have less than that (but the compression is more or less equal in each cylinder), your engine is worn out and will need rebuild.
If you have one or two cylinders that are very unlike the others, it may be that your head gasket is blown, or worse, but you'll need to open you engine anyway.
Hope this helped :shifty:
EDIT : If you're going to open your engine anyway, it's always a good idea to replace your valve seals, it's not expensive to do and can avoid you some headaches ...
