240 warm up loss of power

My 1982 240 D will loose power shortly after warming up, particularly noticable when attempting to accelerate or go uphill. During these times I can manually downshift the automatic transmission and the engine speed does not respond. Once I crest the hill and reach 45 miles per hour there is a sudden surge in power. I have changed all filters, and two different diesel mechanics in our area cannot figure it out. The car is a wvo conversion, and the same phenomenon occurs wether on diesel or veg. On a cold morning or when the car is first started this does not occur. Any suggestions?

Stripped valve locking nut 1983 300D - Now what???

Hi all; Was doing my first valve adjustment and am convinced that the #6 valve has a stripped lock nut. I'm concerned that the valve stem itself is stripped, but when I tighten down the top (adjusting) nut, the locking nut just glides with it, and I CAN get a ton of clearance for the rocker arm. What's involved in changing the locking nuts? Do you have to remove the cam, etc? I know that either (or both) the threaded valve stem or the nuts can strip. Typically, does the nut give out first? Hoping to hear that I don't need to pull the cylinder head.

Sporadic oil pressure needle

!985 300CTD;150,000miles. During a 7 hr trip at highway speed the oil pressure indicator needle stays at a constant "3". When reducing speed & coming to a stop or idling the needle bounces (is not steady) at just under "2" & a "thumping/knocking" sound comes from the gauge area but is not heard when the engine rev's up. The engine runs quite well & pulls strong. The oil/filter was just changed & I have used synthetic diesel 15w-40 in the vehicle for the past two oil changes@5000 miles per.

Putting gas in a diesel - What happens?

Hi there. Just was curious about what exactly would happen if someone filled a diesel cars tank with normal gasoline. I know this is a bad idea. I'd NEVER do it, of course. Just was wondering what the effect would be. It's bound to have happened by accident at a full service station to someone. Would it start? Run? Explode? Would this make for a fun filled, exciting episode of "Master Blasters"??? Anyway, was just wondering and hoped someone would know. Thanks so much... NSA - Hazleton, Pennsylvania, U.S.A.
