Golf VI TDI, 77 kW (CAYC) Feb 7, 2011. #4. Yes, injector seals is a must. At least, this is what my mechanic says. If you swap the heads then you need to re-do the timing belt job (I think this is pretty understandable). Also, you will need a new head gasket, those one-time-use bolts for the head, engine mounts and so on. We’ve seen them last on average over 200,000 miles without any serious engine damage since they were built on the premise of TDI engines. Several times, we’ve seen cars run at 400,000 miles if they hadn’t already run that far. Is the VW 1.9 TDI a good engine? Engine 1.9 is considered to be the most reliable TDI with 90 hp with Bosch pump. When the first 2003 TDI engine appeared in 2.0, the 1.9 TDI slowly began to pull. Unfortunately, the new diesel proved to be more unreliable. So, if there is a choice between a 1.9 TDI and a 2.0 TDI car, choose the older generation of engines, even though it offers slightly worse performance, and certainly better choose the 130hp 1.9 TDI poplar grove il.

Id' certainly look into boring an engine, however you're looking at alot of money for custom pistons as available oversizes are typically only .25mm over. Stingray RT supposedly has a piston at 83mm but I havn't figured out how to get him to sell me any. For $2000 extra, the 2.0 TDI is a clear winner in my book. You would need to chip the 1.9 to get anything like similar performance as the 2.0 (which, in stock standard according to UK and Ausie road tests is only 1sec. slower than the GTI to 100km/h ). I would ralso ecommend 17" boots with 225x45 rubber as a sensible option. Our verdict on the Volkswagen Touran 1.9 TDI. The Touran is a quality package in terms of safety, style, ride and handling. It's ahead of many of its competitors in the compact MPV sector. As with most of the vehicles in this market, the diesel engines are likely to prove most successful, offering the best economy and car-like performance. Costs TDI. 2003 jetta tdi. Aug 8, 2011. #1. A week ago I was driving home when all of a sudden my tdi started blowing black smoke when accelerating. It otherwise seemed to dive fine. No engine light on either. I took it in to a repair shop who spent 3 days unable to figure out what the problem was. They then did compression test and got 450, 410, 376 a3P2OSj.
