DB 1210 w loader and cracked block - price check?

If the engine is tight, no blowby under load and hot(and you gotta load them up to tell, and no burned valves (let it scream while checking for blowby and then idle it down fast. Shouldnt pop any in the exhaust then I'd grind that mess out and get it welded.

If you are going inside the engine parts are high. If I remember right bearings are available 30 under on the 1210 cranks but only 20 under on the 1410's. I've never been able to turn one out. When they are worn they are usually worn beyond spec. Last crank I bought was 800. They have to be matched to the blocks too.

Pistons used to be available up to +40. Its parent bored (no sleeves) though there is a sleeve available to take it back to standard.

Last one I built (3 yrs ago) ran right at 4000 with everything (including cleaning injectors and checking the pump). Thats plus my labor. I did have the machine shop assemble the short block but that was only 150.

Sometimes even if they dont match they will go a long time. I've not seen problems on the lower hp applications. Big problems with 1410's if using the different blocks with the higher fuel delivery and turbo. To a lesser extent it can be an issue with 1210's.

I cant recall how the 995 balances the engin. I know they have rear mounted pumps but I cant recall how they do it. 1210's and 1410's use fluid dynamic balancing with the front mounted hydraulic pump. If you notice the cranks dont have counterweights. Over time, these will fatigue right at the mid line of the crank when they dont match. Usually when I get a mismatch in its a broken crank between the 2nd and 3rd main bearing for no apparent reason.

With all that said. At this point matching cranks is almost impossible. There just arent enough left and the reman's if you can find them dont come with a history. Thats the main thing that I tell people when I build an engine. I normally warrenty the engine 12 months 1200 hours but DB engines that I have to put a crank in its 30 days, 100 hrs parts and labor plus whatever parts warranty the crank builder puts on it.
