I am taking car off road for winter. Other tasks to take care of. I will resume this thread in spring. Thank you all for help.

I have thought about that. But it seems to take a lot of water to work in. Was a few hours driving in downpours with lots of pooling water on road first time. Few good hose soakings of DEM could work. I'm looking at it again today. Was nice and clean with no heavy rust or corrosion around it last I ...

Hope it all went well. Done 15 of these heads, Never seen a bad piston yet from valve contact. And never seen a warped head even after some real hot cooks. Check used valves and lap them in well. An easy job really. I have come across 2 broken head bolts...both came out by carefully turning with pic...

My guess is it is caused by one connector short throwing many false trouble codes. But which one?????

The tricky part is the codes all come when wet at once...Can the DEM set ECM codes? Today is a dry day,ECM Codes cleared and not returning for now. I will check out the DEM anyway, watched a good vid on it and seems worth checking no matter what. Thanks for info!

Finding only pieces of this here so thought I'd ask. Was driving in heavy rain (All systems perfect for a year before) and suddenly got an ABS?Trac control message...Then Brake system warning, then Reduced braking warning, then gauges began to stop,then active traction settings OFF, then reduced pow...

Interested in this internal PCV system, are there passages NOT accessible from outside block? Have of course done all the hoses,breather box and cleaned the ports on block making sure they are clear to internal galley. I have been using copper pipe and silicone hose to replace the plastic piping on ...

Thank You, sounds plausible How do I get to Mikes pics? New user today...
