(03-27-2014, 05:58 AM)offroaddieselhu Hi,I have problem.I have OM604(w202 220D with lucas pump) and now i have om601 pump on this engine.but I not runing good.I was 15 ATDC.Good start and run,but much white smoke and idle is horrible.10,20 ATDC it was same.Now i running 14 BTDC.not good start,but engine runing when idle so littble bit hard,some black smoke and high rpm not much white smoke when before.Injectors are good.pressure is 110-115bar.But injectors are original for rotary pump.om601 pump is from w124 200D,same injectors pressure 115bar.Om601 pump is stock.I'm desperate.please help THX
I've made this engine about 6 years ago. This is a socalled basic engine, that has 0.9-1 mm ATDC.
If I'll make the new I'll messure the new setting and I'll writte you.

(03-29-2014, 01:03 AM)Tito Rotary pump injectors and inline pump injectors don't mix. They have different kind of needle lift I thought.
The lift part is a possibility, but I don't think it should matter too much as long on the pop pressures are set correctly for either a rotary or inline. Too much injector pressure on a rotary will junk it real quick
'82 300D -3" straight pipe, ALDA deleted, 3in1 glowshift gauge, HX30, egr-less manifold, A/W intercooler
'14 Ram 6.7l cummins -G56 handshaker, wishing it was deleted

Left is from a VW 1.6 turbo diesel and right is from the Mercedes 601/2/3 n/a engines. Can't find a whole lot of info on the VW injectors. They look exactly the same
I have some brand new injectors laying around here. But no pop tester. I'm quite curios what's the difference. I can not imagine the difference in pop pressure result in a totally different Bosch number.
