Added electric fan. Will be using a temp activated switch in the end but used a manual switch for now.

Put in about 10 miles yesterday. Runs well, about 185 f and about 5000 egt averageish. Had bonnet off during drive. I can see smoke/vapor escaping out oil filler cap under load. Doing compression test this weekend to see what's going on inside.

5000? Or 500? 5000 is impossible and 500 is very low if you are working it.

You can drill and tap the coolant outlet to use a thermo-switch.

500, went up over 600 a few times but wasn't pushing it too much

500 F ???? That is way low. Really, all that matters is the temperature with full throttle for extended periods. The temperature means nothing at part throttle.

Once I get the bonnet/bumper/tunnel boot on I will have less distractions and will take better note of the EGTs on hills/load. I just glanced down a few times. Was looking in rear mirror for oil slicks most the time.

400 is what it cools down to @ idle so 500 going down the road is ice cube cold. 800 would be a normal going down the road temp. If you cant get over 900 then the engine isn't getting sufficient fuel.

Ok. Some help

Pulled head due to smoke out oil filler and some white/grey smoke out tail pipe. Getting some pressure into rocker cover pushing oil out cover seal.

Here are some pics. Bores look a little shiny, head surface looks good, used feeler and straight edge, not watped. No visible cracks.

But I did notice 5 out of the 8 valve seals were lose and towards the top of the spring. Not sure if they were blown up from pressure or what? Could this be causing my smoke issues? But probably not the pressure though.

Head gasket didn't look horrible and didn't have noticeable faults.

Headed to machine shop tomorrow to have pressure tested.

I know the block would beifit from rings and some deglazing based on shiny bores, but totally dismantling the block isn't in the cards right now.

Maybe valve seals are worn? Well the machine shop can take care of all that and reseat the valves.

I think you are jumping the gun... Smoke in a diesel is almost always just from the injection system. White smoke is unburnt fuel, from being sprayed in a bit late due to timing or spray pattern. Any crankcase oil that gets into the cylinders will burn cleanly and not form any smoke.

Some vapour in the crankcase is normal. I assume you have not had the PCV system hooked up?

Question:

Is the TDIs valve space supposed to have positive or negative pressure? Or neutral?

If the PCV is working it should be slight negative right? No?

Just trying to learn what is normal.

I have had the pcv system hooked up on the last few drives. The smoke coming out filler neck I can see and smell when bonnet is closed at a stop light. Enough pressure to be pushing a good amount of oil out valve cover gasket. Definitely combustion gases in my mind.

Wanted to check things out under/in head for peace of mind before hitting the road for a few hours to wintergreen (goal).

Also if I look inside head from exhaust ports, the exhaust cavities "valve stem" visable are oily (wet) more so on front chamber.

If you put you hand over the filler at idle, there should be some suction. As you rev up it might go neutral, but should not push gas past your hand.

All if the PCV system is working.
