Hello,
I bought a vintage chevy p30 motorhome with a transplanted 7.3IDI NA and an allison 545.
I was a silent reader for a long time and now I have a few questions.
1. there was a coolant heating radiator for the cabin connected. It came somewhere from the block, through the radiator and went back next to the oil fill in. (The red line Picture 1). Is it okay to connect it directly how it is now and add later on the heater in line with this again?
Later I want to add an espar diesel heater which should heat the hydronic system in the motorhome and the cooling system in the engine. How do I connect it the best way?
2. The guy who put the engine in used plumbing parts to extend the oil fill in. I took them off and put duck tape on it. The Oil fill in has a thread and the oil cap doesn´t fit. Where can I buy the insert to asdd an oil cap directly on the filler again?
3. Since it is a GM base I have the hydroboost brake system. I need an hydroboost steering pump.
(https://www.carpartsdiscount.com/power-steering-pump/chevrolet~p30.html?3593=477361) I figured already out that there is a bracket for it where I can cut out a part and then use it. Is it true? and If yes - where can I get it?
4. I know that the original configuration are 2 batteries in parallel. But this is a design that is 20 years old. Did anyone have success with using one high amp battery for starting?
That is it for now.. I'm really thankful for all help I can get. I drove this monster 1000 miles down from Portland to Orange County and I'm actually impressed how the 7.3IDI handles. I really want to keep the engine in this motorhome.
Thank you very much and best regards
Clemens
