The 4LE-354 (wastegate) turbo achieved about 12 psi peak. I try not to run past ~1000°F and I don't take the rpm to the redline. The 4LE-456 didn't perform very well when used in this manner. The most boost I could get under the roughly the same conditions was ~8psi. Very little boost at...

Any luck finding a rod bolt?

With few exceptions, they are "alternators".

There is an idea floating around that the 6pt rod bolts are failure prone; can you check and see what you have?

You tested one and it was a stream?

I recall in other threads posts indicating that it is, in fact, a spray. I have not observed testing of one of these injectors in person; but I have a hard time believing that ~2kpsi through a tiny hole won't be a spray.

If you really want a quiet truck; why don't you install a full, rear exit exhaust?

The LDT465-1C, LDS-465-1, and LDS465-1A have the same timing: 20°BTDC so no change has to be made if you already have an LDT. The naturally aspirated LD series are 25° BTDC and the highest horsepower version, the LDS465-2 is 22° BTDC.

It is really hard to say if it is still important. The continental literature claimed it was done to "eliminate the requirement for high additive oil to prevent excesssive ring groove carbon formation." Has anyone had ring sticking with modern oils? The piston bowl is cooled on all engines.

Somebody once posted that heater kits were furnished with 195°F thermostats to improve heater performance. Is this true and has anybody used one?

Here is another, perhaps more succinct explanation: http://yarchive.net/car/engine_water_restrict.html Copied the text from that link: From: John De Armond Subject: Re: Cooling system fact or fiction Date: Thu, 23 Sep 1999 06:12:19 EDT Newsgroups: alt.autos.rod-n-custom,rec.autos.rod-n-custom...

Sorry Rick, your idea just doesn't hold water. Heat flows from hot to cold at a rate proportional to the difference in temperature. The hotter the coolant gets the slower the rate of heat transfer from the engine to the coolant. Slow down the flow of coolant, and you agravate the problem...

I've done testing with normal thermostat, high flow thermostat, and no thermostat. The operting temperature decreased with each step. Magzines have done the same tests. The thermodynamics agree with t. Yet, somehow, this myth will not die.

Tractor owners commonly cite this problem...

I noticed it at our local farm store and like the color better. Plus, it is available in quart cans. Anybody know if I can spray this with a wagner gun?

Schwitzer 4LE-456; 11641831-1. Divided inlet; each half feeding 360° of turbine. The diffuser has vanes. Appears to have the same turbine as the 4LE-354 but has a larger diameter 60mm inducer and taller exducer blades.

Schwitzer 4LE-354; 10945184. Wastegate turbocharger. Divided inlet; each half feeding 180° of the turbine. There appears to be two different compressor inducer sizes. This one is 57mm, my other (with damaged turbine) is 54mm.

Actually, I was going to slightly turn down the fuel and be happy with it. However, I just bought a brand new 4LE-456 (LDS-465-2) turbo for relatively cheap. That turbo has a larger diameter compressor inducer, taller blades at the exducer, and a vaned diffuser. Gonna try this one next. I...

it took some patience, but I found a rebuilt 4LE-354 (LDS-465-1A) turbo and installed it recently. It does make a difference. With the 3LM-39 (D-turbo), the boost came up quick but so did the EGT. My FDC is compensated, and going up a hill, I would have to take my foot out of it pretty...
