 How do you install a turbo timer and a blow off valve on a 2003 VW Jetta 1.8 Turbo

As for the turbo-timer -- why do you think you need one? Like all other turbocharged engines, you should idle the engine for about a minute before shutting down. This cools the turbocharger bearings sufficently by flowing oil thru it. Besides, you should be running 100% synthetic oil that will not succomb to the heat in the turbocharger.

Replying to: sossowski5 (Jun 13, 2006 2:22 pm) http://www.vw.com/vwcom/content/objects/pdf/service_maint/engoil_gas.pdf Ands here is VWs "official" list of approved oils in North America http://www.vw.com/vwcom/content/objects/pdf/service_maint/oilchart.pdf It sure looks to me as if you should be using synthetic oil. I know I would only run synthetic oil in a turbocharged engine. It sounds to me as if you are more interested in how it "sounds" and the "coolness" of a turbo-timer instead of making your car last... everyone has their own priorities. 8-) As for a "louder" BOV... have you tried removing the muffler from the existing BOV?

Replying to: sossowski5 (Jun 13, 2006 6:24 pm) Who changed your oil? VW sent a letter to all 1.8t owners advising them that this engine requires ONLY synthetic oil, not conventional. Sludge WILL build up in your engine and since you are using the incorrect oil, VW will not honor the extended warranty. |

Replying to: sossowski5 (Jun 13, 2006 6:24 pm) Also, you are mistaken about the REASON for a BOV... it has very little to do with the oil-seals on the turbocharger bearings. Instead, the BOV is there to keep the turbocharger shaft from twisting which causes unwanted harmonics that can cause catascrophic turbocharger failure. May I ask you what you think a "turbo timer" is and what it does?... again it has very little to do with the turbocharger bearing seals. Your choice of ENGINE OIL is farrrr more important to the turbocharger bearing seals than either of the items you are asking about. How many pistons have you held in your hands while rebuilding an engine? Have you seen what the use of dyno-oil can do to the inside of your turbocharger bearings? I wonder if you are you trained in engineering... or perhaps you should be listening and learning from those of us that know a thing or two about engine design. |

Hi, I've just got a used jetta 2001 GLS. I found the engine oil level drops quickly (1 quart per 1000 miles?). But does that mean that I don't have to do oil change? Because before 3000 miles most of the engine oil has already been changed. thanks, Quan |
