RE: [Biofuel] Bad news for Diesel driver
This is done on small 4 stroke RC engines all the time. The problem is lubricating the rotary valve and controlling leakage. RC's use lots of lube in the fuel to deal with this issue. Also standard valve has the advantage of self-sealing on compression. Not so with a rotary valve. There is always the 2 stroke Diesel if you need minimal head/valve displacement But you need a forced air supply (IE: turbo/blower) to get the air in the engine.

Re: [Biofuel] Bad news for Diesel driver
Hi John, I'm drawing a blank wherever I look, what is a patical dish, please? The valves in engines designed with durability in mind already rotate, but I wouldn't know if they would have the force required to rotate this valve you mention. Thanks...

Re: [Biofuel] Bad news for Diesel driver
I don't believe that with the high compressions required of a diesel engine it is possible to have a non-interference design. To get the high compression there is VERY little space at TDC. I don't think there is any way to design around that. If the valves were recessed into the head then there would be more space underneath them. The proportion of displaceable space (where the piston travels) to non-displaceable (everywhere else) has to be very high (20:1 or maybe 22:1) to get this compression. That doesn't leave much of a possibility to play with. I don't think in this matter there's any way to blame the engineers. I could be wrong, but I would be shocked to hear if anyone has any evidence that a diesel engine was non-interference. (Tho come to think of it, some of those lower compression super low rpm old time boat diesels might be that way.)

Re: [Biofuel] Bad news for Diesel driver
Why all the acting like engine damage due to a timing chain or belt failure is something new, when this possibility has been around for quite some time? Longer than the 25 years indicated The risk is born from pushing the envelope, so to speak, to get the best possible performance from an internal combustion engine. Like everything there is a trade off. An increase performance over most of the engine's life for adding a maintainence item, as well as the risk of destroying the engine if that maintainence is ignored or stroke of bad luck occurs. I have to think the record would reveal the trade off a positive one.

Re: [Biofuel] Bad news for Diesel driver
I'd like to purchase a diesel vehicle, as my next, and wonder what my choices are (REply) Hello Jon, Don't know about the rest but you should be aware that the VW engine has a very serious design fault. If the timing belt breaks the engine will be destroyed. I don't know why vw didn't shorten the valve stems and recess the valves in the head, and maybe recess a small area over the piston so the valves would not make contact with piston and destroy the engine if teh timing belt failed. That just happened to me, I had less than two thousand kms on a new belt and the technician said that snow probaply got behind the belt causing the motor to go out of time. It cost me over $2000.00 dollars to fix. On the other hand I have had a vw engine go 1,000,000 km without problems before giving up and I really don't think it was a fault with the engine that it finally gave in. It sure doesn't make for pleasant driving wondering if the timing belt is going to hold up. PS The sympatico mail server crashed, we were without mail for a day. It is now supposed to be fixed but I see a mail message that I sent to the list came through twice and I only sent it once. I have been trying to call sympatico to retify the problem but the wait is so long I can't get through. I hope this doesn't come through twice.

Is the mechanic that gave you the snow behind the belt excuse the same one that changed out the Timing Belt 2000km ago? Frankly, I'd suspect that he didn't have the proper tools and botched the job and now he's trying to cover his butt. It's well known that you should never use the mark and pray method on a TDI. http://forums.tdiclub.com/showflat.php?Cat=0Number=927828page=fpart=allvc=1 Also, it's worth mentioning that this isn't a design flaw, let alone a serious one. It's simply a characteristic of all interference engine designs. To call it a design flaw is like saying gasoline engines are flawed because they have spark plugs. Audi, Honda, Volvo, VW and others have been using interference designs for over 25 years. In fact, most high compression engines are interference designs.

everything you will find in the US and a couple that would be very hard to get your hands on. For 2-3 thousand, your choices will be limited to somewhat old.
