i didn't change any gaskets and haven't had any problems
Will i need new oil return and turbo manifold gaskets ?
My recon one had minimal movement, which I put down to heat expansion? But no it shouldn't have that much lol
It could be that I'm wrong, but recently I read that turbo's spin at 100,000+rpm and I can't imagine that will be very good at that speed. No doubt it's balanced correctly, so shouldn't actually move that much once it's spinning but that is significantly more than my recon unit had.
If a company that deal in turbo's has say's it's fine, then it must be. I'd say yours and the video are about the same
a small amount of raidial play (up and down) is fine and normal as these turbos use a journal bearing so the shaft floats inside the bearing on a pillow of oil, when the turbo is drained then this will appear slack
axial play (in and out) is not acceptable and is a sign of a worn or failed trust bearing.
thats ok then, its not moving in and out, just slight movement left, right, up and down
I have done mine twice (pd150) and have just done my brothers 2 days ago (pd130), every time i have gone in from the top,
first off remove the top IC pipe
then remove EGR valve, good time to remove the pipe and fit blanking plates if you haven't already?
then get underneath and remove the 3 bolts from the down pipe and then oil return pipe and finally the TIP (a couple of 10mm bolts, 1 under egr valve and other on top of intake maifold) long nose mole grip work a treat for the clip on the turbo end.
back from above now,
remove the intake manfold and the oil feed pipe, careful not to twist it as it becomes quite brittle over time and then finally remove the 8 12mm nuts from the exhaust manifold.
if i remember i think i had to take off the rocker cover on the pdp150 to get the turbo out from behind, i think was due to the egr cooler.
hope this helps a bit, i can now remove a turbo in around 1 hour now...
If you go underneath it doesn't but it you might as well so you can clean it nicely....
Unplug the ECu or cam position sensor ( if it has one ) and crank the car over for 10 or 15 seconds,
That will get the oil circulating.
