Your old 300D still pulls pretty good up to redline, especially with 80% WVO in the tank...bet that 325 will out run it though.

I did a 60 mile Italian tune-up on my 240D with MMO in the fuel to fix a rough idle (just before the timing chain broke) and it ran much better afterwards. That said, I'll bet there are a number of things that you could break just from flooring a car that hadn't seen serious throttle in a few years. Change your filters first, check your linkage, then look at valves and chain.

BusyBenz, I lost track of the thread. It was Jimmy Joe who had problems after an Italian tune-up, not you. Sorry about that.

Rich, you must have looked into this - how extensive a swap is a 1.9 TDI into a Vanagon?

Well, she still is driving like a slug.
But I have a hard time believing that I did damage...
no extra noise, still runs smooth, just doesn't have the power that it did...
got new filters to install and diesel purge this week sometime when I can find time...
thanks for the input folks, had to get away from it for a little while, really got me worried.

doggone it, I sure love that darn car....

That's OK Sixto, I kinda figured you had me confused with somebody else!

???????????

4,800rpm is about all a 603 is good for. My IP cuts out at about that. As long as the engine is under load rpm's won't hurt anything. I love the way a 603 sounds at 4,800 what a sweet scream! At 3,500 they do pull strong.

On the parkway a couple of weeks back I got on at the bottom of a steep hill. Now that parkway is an old road and you pretty much have to stop before getting on. I put my foot to the floor and ran her to 4.8k in three gears, the temp never got much above 90C.

Turbodiesel have you ran your E300D past red line yet? Thats just for show the IP cuts out just above.

Back to basics. Have you checked the line from the manifold to the overboost protection switchover valve (what a mouthful!) to the ALDA? Have you checked that the wastegate isn't stuck open?

Maybe it just feels like a slug becuase you've experienced the dark half of the accelerator pedal travel

Not yet.. won't get there, it isn't running right. When I fix it (waiting on the sensor) in a few days, I'll give you a full report

Naturally aspirated. No alda.

Truer words were never spoken. I have worked on bunches of them. I even got factory training while working at the dealerships. "Fast but they don't last" is often an apt description for most of the beautiful offerings from Ferrari and Lamborgini. None of them can make a U-turn in less than 5 traffic lanes. Caster has it's disadvantages.

After all, they aren't Porsche 911s, eh?

You are in for a treat! These cars have guts! This diesel can do a burn out and the traction control does have to work a bit if you get on it!

btw for some reason these cars seem to be very sensitive to dirty air filters. When my friend got his the filter looked a bit dirty but not to bad. He swapped in a new one and gained almost 2mpg! Since your working in that area you might want to check it out.


Back on topic I don't think you broke anything. The drive lines on these cars are pretty tough. The way I look at it the W126 at least in euro trim had 300hp, and was built for autobahn use. So a 150hp diesel isn't going to be able to hurt anything. Pull the valve cover if you think you hurt something,but I don't think you did.
