Default turbo supply line

I know I had asked about the supply line before but if the turbo is still good and the line/fittings are not leaking what is the likleyhood that the oil is coking up in the line? Is this something that shold maybe be replace every so often to prevent the coking problem?

What coking problem? You use synthetic oil and there is no problem.

If you are not using synth, start. Dino oil will coke on the hot surface of the bearings in very minute amounts but when it is spinning 30,000 - 60,000 rpms even a small amount is destructive over time. I have not seen it accumulate in other areas of the engine.

Reading the following PTCruiser Turbo User's Guide should provide the information that you need about the importance of using synthetic oil and changing your oil supply line.

http://www.ptcruiserlinks.com/forum/...albums229.html

In extreme conditions Synthetic oil will also coke up. Hot shutdowns should ALWAYS be avoided to prevent oil coking.

Don't hesitate to contact us should you have additional questions or concerns,

How? It takes carbon to make coke and a full synth base oil should have none. I know it can burn at very high temp but how could it form coke? Just asking.

I just spent the last 30 minutes typing a thorough response only to lose it because I was automatically logged off due to inactivity.

You and I have spoken about the coking issue in the past here:

Turbo problems... I hope


The jest of the lost post was we have been doing this for 15 years now and have seen failures in both Synthetic and non-Synthetic environments. Oil does more then lubricate. It keeps impurities in suspense so they can be captured by the filtration system. Liquids (Fuel, coolant, water, grease, etc.) and smaller particles are not filtered out and play a part in breakdown and coking. This is why changing oil at regular intervals is so important. The longer you wait the more debris remains suspended in your oil. All brands are not alike. We have seen issues with Royal Purple in turbo applications. Stick to the name brands.

The crux of our response to your post was to prevent members from thinking that it was "okay" to subject their turbos to hot shutdowns just because they were running Synthetic oil. Hopefully the abbreviated explanation above is enough to convince members that it is not a good idea.

If you still have questions give us a call. We are here to help answer them.
