    P38A P38 2.5 dse engine noise?

    Hi Guys, So far so good, the new engine is running fine no odd noises or anything so very pleased with it. However 🤓 I find it is very smelly and smoky (white grey). I think it is running a bit rich. Temperature is stable at idle or driving so no overheating. Idle is set at 750 rpm Injection...

    I did remove the coolant radiator, oil cooler and intercooler just not the condenser.

    Yet another update,installed the new engine yesterday. It lined up quite good to the gearbox, I thought it was going to be a tedious work but eventually it went in rather fast. It already runs but I still need to tighten the head bolts another 90 degrees as per rave. Of course I brother...

    Small update. Omdat engine is out, managed to take it out and leaving the torque converter in place. Engine mounts are shot. Waiting for them to arrive and good weather to get newly built engine in. Alas still need to remove bearing at the back in crank because new more was originally a manual...

    I mean the buckets that sit over the valve assembly. On the inside of those buckets or tappets there is a spring loaded part. When in use they are filled with oil. When they get stuck the valve clearance is no longer correct.

    The tappets are out actually but they don’t seem to work properly. The inside part that touches the valve stem is spring loaded. Some of them do not move when I try to push on them, even with the oil out.

    Hi Guys, I'm in the process of assembling the engine. I was cleaning the hydraulic valve tappets and found that some of them do not move, like half of them are stuck. Can they be dismantled or is it better to replace them all together? Secondly, Once the lower chain is ligned up between the...

    Ok seems a good idea, I’ll try this first with the old bolts. I’m using new bolts with the new gasket.

    The head gasket had 3 holes in it, I think that’s the largest available gasket. I could coat it in VHT copper cement spray for head gaskets in an effort to fill in the gaps.

    Well I’ll have to shorten the valve stem also to avoid issues I suppose.

    I’m going to bring it to the machine shop. I think the valve seats can be re-worked so the valves sit a bit lower to maintain clearance

    I need some advice concerning a cylinderhead. As you know a have a second engine on hand that currently is in the process of refreshing. The engine as it sits is now completely dismantled. I checked over the crank and polished the bearing surfaces and they measure all within spec as per rave...

    Well, the noise is from the injection pump housing. With a stethoscope it is clear that this is the source, with the intake installed it resonated a lot and so it seemed at first to be coming from the ofh. I have a second pump on hand and will replace it next weekend. Actually I bought a e39...

    Morning, Just sticked my head under the bonnet again of the p38. I've let the car idle a bit, when cold no noise at all, when getting warmer the knock appears. Strangely enough I never thought about touching the oil cooler feed and return lines, I noticed only one of them is warm, the other...

    P38A P38 2.5 dse engine noise?

    Well the reason I asked this because I found there is too little oil in the housing upon removing the filter. There is oil in there and the filter definitely filters the oil. The noise my engine keeps making is almost undeniable from the ofh. I took a look in there but there is not much to see...

    Quick question, the oil filter housing (ofh), should it remain full of oil? What I mean is, if you let the car sit for a day and you open de ofh should it be full of oil? I would think so but I wanted the opinion from someone here. It is not the case for my car

    Alright, I think I'm going to attempt a timing chain replacement myself. But first I need to source the parts and some tools. I use Autodoc for parts orders. Does anybody have any recommendations for timing chain kits, I see there are different makes available from cheap to expensive. I did...

    I opened up thee re-circulation motor and there is no variable resistor in there only pinions and a motor. I also noticed there are no marks on the pinions for that one. On the other hand there are some marks on the pinions of the blend motors in the center. It will be trial and error, I'm...
