Well had a good trip down to Williamsburg V.A.. The old girl did good down and back at 65 to 70 mph. Got about 10 to 11 mpg. Only problem is somewhere and not even sure how I lost one of my awning rafters. Does anyone know where I could find a replacement one. I only need the outer end that slides out and hooks to the awning arm.

Well haven't done much to the old girl this year. I fixed the furnace by replacing the electric valve. I also wired the stereo to the house batteries so we can play music with out killing engine battery. Leaving in about a month for Williamsburg V.A. for a little over a week camping. That's all I have for now the 4l80 transmission has been doing great so far and should be a nice ride down to Virginia.

Since I'm still waiting for ONAN parts... I pulled out the Suburban furnace unit and did a complete repair/ rebuild out of two units to make a good one. Put her back in and yes!! Success! Now I have a toasty RV! I posted info videos on the YouTube....

Managed to get a few NY trips under our belt on the P30 and only one mishap with the governor gear getting stripped. fixed that pretty quick and was back on the road. Now looking to go a bit further with the Allegro this Fall down further south.

Yeah the pumps seize up, which is part of the problem. The other is that the little air tubes on the manifolds rust out and leak. My replacement engine is a GM Performance crate engine ("off road use") so it didn't have the air ports on the manifolds. They make an idler to replace the air pump. Not sure. If memory serves removing it makes a pretty long run from the crank to the alternator. The belt slips unless I keep it really tight.

The mechanic shop that removed all that air pump stuff on my mh left the pump itself so they did not have to find a new belt. Well it seized up on us on the major trek and we were stranded along side of the freeway in eastern Montana. Had a great mechanic shop there. They removed the pump and got a replacement belt out of billings mt. So we were down on Fri and Saturday. But we were set up properly when we hit the road again. Long story short---do the job right the first time.

All hoses lead to this crazy air pump thing up front. I have no issue removing it and redoing the alternator belt but I seem to think that this belt is not the same one for the alternator. Could be wrong but will look. From there I'll plug up holes for the hoses and see how she runs.

Mine doesn't have an EGR, but it does (did) have a belt-driven air pump. They are problematic. NJ doesn't have inspection (visual or otherwise) so I removed it. Just need a longer belt for the alternator.

This engine has about 3 hoses hooked up to the air filter housing. One looks like a breather (foam filter on the 10 position) and two other plastic pieces at 3 and 5 o'clock. These hook up into some belt-driven unit in front of the air filter. Guessing some kind of emissions system.

I was wondering on the EGR. I have her parked and running and you can detect a low whistle. Put her in gear and the vacuum drops a bit. I would consider it a great victory if I could just stop that giant sucking sound when driving.
