Re: oil change

Some advice when changing the oil on the SVO ... Ford service manual states to remove the coil wire and crank for ten seconds until the oil pressure comes up a bit. Then re-attach the wire and start the engine. This prevents the turbo from spinning at speed before the oil is pumped through the filter and oil passages. Also manual suggests to let the car idle for ONE minute (after driving) before shutting it off. This removes a lot of heat from the turbo , preventing the oil from cooking on the bearings.

Cobra, I was talking to a Motul rep at a car show and he was telling me about his Motul oil. He said a lot of turbo people use it because some oils break down at high temps like a turbo would provide.

This is true, at work newer turbo'd VWs are all comming back to the dealer for low oil pressure and such. VW released a new tech tip or TSB saying that they are discovering that the regular "fossil?" oil that all VW come with are leaving huge deposits their turbo'd engines' oil lines. I saw this first hand when a VW tech showed me a 1/2" hard oil line that was completely blocked up with only a pinhole for oil to go through, no lie. He told me about the new TSB and said that VW is updating their oil filter with a larger capacity filter and saying to only use SYNTHETIC oil on all their turbo'd engines, Audi too.

I prefer to floor the accelerator instead when starting after an oil change. When you pull the coil, the injectors still squirt but when the EEC sees WOT TPS voltage, it shuts the injectors off. No point in washing your cylinder walls down with fuel and no spark!

What!?! Floor it with no oil pressure, why doesn't the injectors squirt at WOT cranking, arent they designed to full duty cycle at WOT?

If you really wanna be picky about it, i say disconnect the coil connector harness (primary side) instead of letting the secondary high voltage arc to ground and about the fuel thing, just reach under the driver seat and unplug the fuel pump relay.

OR

What mike said makes sense too, unplug the TFI connector and the ECU never sees crank signal thus no spark or fuel is added. Hmm never thought about that.

I should have said it only cuts fuel under WOT during starting conditions (if your TPS isn't adjusted properly, it will start and race to redline, I can't think of a worse stress on the aux shaft or bearings) Ford programmed the start cycle like that as a safety for all the people who were conditioned to starting carbed cars with the throttle.
