Has to be the case.

With no seals in the IP, you cannot expect the same delivery pressures after 300K miles. Nothing mechanical can run without any wear.

Yup, that's a lot of cycles with metal to metal contact. I don't know any real way of testing them for pressure/capacity and if you're going to open them up for inspection you might as well rebuild them. I guess it's just one of those things that is reasonable to replace after 300K miles, or so (timing chain, oil pump, oil pump chain, etc.). At least they don't do any real engine damage when they finally do fail.

Does anybody have any experience dealing with this company?

Adsitco has a spotty reputation for costumer service (returns, problems, etc.). My indy shop will not deal with them because of past problems. Also, I don't see how they can do a decent rebuild at those prices.

With Metric Motors you also get Glow Plugs, Fuel Injectors with the Injection Pump. And 4 year 50,000 mile warranty.

You get what you pay for.

My favorite machinist talked to the folks at adsit. they just bore out the engines and put in oversized pistons. No liners, no truing the block. He was not impressed with their methods.

What's the point of paying $4-5K for a half-ass rebuild, if you don't want to pay for a real rebuild you might as well take your chances on $1000 junk yard engine (it's a cheaper gamble).

Exactly.

But on the matter of injection pumps, I have done a good number of the diesels and used the high mileage injection pumps with excellent results. My 83 240/300 with the euro pump runs so smoothly you would swear it is a six cylinder instead of five.....with a pump that now has at least 180k on it. Actually I don't know how many miles as it was imported from europe and the speedo was changed so who knows how many miles it has?

We have never touched them except for normal adjustments....no seals ever.

I have in fact changed several pumps on faulty advice and never yet solved the problem being chased.

I agree that they would probably be OK, but if I'm going to spend $6K plus labor on a "new" engine I will also replace the IP just because I don't want to have to hassle with it for the following 2-300K.

Thanks for all the help guys. I'll give Metric a call. I have a few specialized requests and I need to know how they can help.

Concerning the short v. long block, it is my head that is shot. I figure while doing some of it, I might as well do it all. The engine is old, high milage and not well cared for by the last owner(s). The rest of the vehicle is being restored, so the engine should get the same. The only problem is that I am running out of steam and time doing the resto and am thinking I don't want to do the engine anymore myself. I also want to ensure it gets done right the first time.

Thanks again for the help,

Steve

It depends on how much of the IP they replace. When I did this sort of work back in the 70s gaskets/seals, tappet pins, pin bushings, cam rollers and bearings were always replaced. After that it depended on what was worn out.
The plunger and barrels were inspected for scoring; if not obviously scored the old ones were put back into the pump.
The pump is hooked up to the test stand and enough adjustments are done to the pump so that the pump can be run up to temp. Ounce the pump is at operating temp. the pump is run slow to simulate starting. If the plunger and barrels do not pass the "Starting Quantity Test" the pump is opened up again and new plungers and barrels are installed and the calibration of the pump starts over again.
Normally you can see of the plungers and barrels are bad and replace them. Rarely but ounce in awhile a well maintained pump with a lot of hours comes in and the plungers and barrels look good but are worn out and you will not know till the Starting Quantity Test is done.
While a lot of the old parts are reused in the rebuild there is still the benefit of each fuel element being brought back to spec. as to being timed to the IP camshaft , the Governor settings, and of course fuel quantity.

I've had experience with Metric, and have been quite pleased.

Can you describe paremeters of the start up test on the plungers and barrels? Also if you are static timing a pump just with gravity feed fuel oil on a car. If you reach your normal shutoff point but the element continues to leak as you go by it at say a drip a second. Is that that plunger and cylinder still considered serviceable?
I personally would think not. If it leaks that bad with virtually no pressure what is going to happen when expected to work at normal operating pressures? A partial flood past the piston? Also I would think it might indicate some other bores or pistons in the injection pump could be even more worn. Less worn is a possibility as well i guess.
How is this going to affect milage as well if you have this kind of wear. One last question since I am a little on a roll here with a guy who has worked proffesionally on piston injection pumps. It seem reasonable to me that a pump internally leaking in this fashion also would even have more difficulty if it was hot. Therefore making hot starts even harder or impossible.
Any comments welcome as we very seldom if ever have the presence of an individual that has worked on the pumps at sometime or another.
Please also excuse what I would think are pretty elementary questions to you. The urge to know the answers is strong though perhaps by many on this site as well as myself. Sorry about the semi hijack of this thread as well.
Metric rebuilders just might know where there is a recent rebuilt engine of theirs with very little time in a car that is either for sale, smashed or whatever. This may be worth talking to them about as well.
The engine warranty might even be transferable. Butter them up with I would not like to see an engine that I had rebuilt go to waste either if possible. Chances are nobody else may have taken this approach . Whats there to lose?:rolleyes:
Also dropped diesel 911 a private message to please drop back here if he has a little time. His past experience, knowledge and hopefully advise are more than welcome. Just thought he may not normally cruise down this thread again. We cannot risk him being the one that got away as well at this point. :D
