Went out today and worked on the bus for a few hours - first time since last November. Cleaned out the battery compartment, got the two big 8D's out, in the tractor bucket and back to where the bus is parked. Everything clean, rebuilt all the cable ends, used my new wire wheel on the grinder to get them all shiny, fresh anti-corrosion grease, popped them in and tightened everything up. Master switch on, battery cut-out on, rear start on, and with no more than two revolutions she lit up! Lots of white smoke and a lousy idle, so I turned the in-line priming pump on for 10 seconds, tried again and instant smooth idle, zero smoke, steady as a rock, 70 psi oil pressure. five minutes later the air dryer popped and I backed her out onto the concrete pad so I can pull the rear wheels tomorrow and start the final steps to have her ready for the road!
And - it was 68 degrees here today, official new record since 1945!

Don't you just love the whistling sound from the turbo I for one could not own a engine without a turbo a N/A engine just sounds weak and are lol
good going Brian
I love that turbo whistle too. All my pickups I drive are turbo Diesel and the first thing I do is... Remove the silencer ring and modify the air box. Sounds like a jet plane taking off. Hehehe.

Hey now, I've got a 73 Challenger with a blown 568 ci v8, and a 4 speed no less. I'm a happy camper.
Ok, Ok it would be really cool to have a turbo as well, but one thing at a time .

C'mon now Brian, you know the rules. You will have to do a reenactment on video so we can have our fix ;D
Brian,
I second what Van said... Unless of course you didn't really start it!!! (Some of us will go to great lengths, even triple dog dares to get video of a new engine start) I have been particularly interested in your repower and it's obvious you are thorough and gifted craftsman.

Guys - I just have no idea how to take video of anything! Apparently both my camera and my phone can - I just don't know how. Sorry...
Brian
C'mon you MUST have a teenager somewhere near you!! All teenagers are genetically capable of figuring out all things electronic...
No worries we believe you
Must've been a stinkin' big smile on your face when she settled into a clean idle, they probably saw that smile from the space shuttle! 70 lbs of oil pressure. I have 40-50 at speed, I think my gauge would break at that pressure!
Cool, cool and more cool...

Don't worry Rick his will be 50 lbs after he gets on road and about 10 at idle I just love it when people come with a 8v71 or 8v92 idling at 30 to 40 lbs you check those with a good gauge 1 was at 6 lbs he was heart broken when I installed a new sender to match his dash gauge
Good on ya Brian. I'm envious of those of you with the talent (and patience) to do what you have done. On the video thing, taking it isn't all that hard, just look for the button on your camera. Posting it on Youtube is a whole 'nuther matter. We're waiting in Port Angeles to get launched after our haulout & I wanted to post video of a launch. They finally did one last night & I must have spent two hours last night between taking the video and getting it posted. Taking the video only took maybe 15 minutes but all the BS afterwards took a long time.
Exactly, Clifford. That 70 psi is a 600 rpm idle, dead cold, 40W oil. Well, cold as in ambient 65 degrees and a little sun on the engine for a few minutes. That's about a 60 pound reading on the dash gauge FWIW, but I was at my local hydraulic store and they had high-buck liquid filled certified 2% gauges on sale for $10, so that is what is on the sensor manifold now. I also modified the source of oil to the manifold . It originally shared the oil feed to the alternator, which is a well known source of low oil pressure readings. If the sender manifold is fed by the same source as the alternator, the alternator pulls off so much volume that the pressure gauge can read 60% lower than the actual pressure. It's like the water pressure in your house - you can have 60 psi of water pressure, but if you read it at the faucet with a hose connected and turned on, you get a very low reading. In my install, I fed both the alternator and the turbo from that oil port on the engine (it's the one at the back near the bell housing on the drivers side of the engine). I drilled and tapped a new port on the output passage from the oil filter head and installed a fitting there, dedicated to the oil pressure manifold only. That manifold is a dead end, it doesn't actually go anywhere, so 100% of the actual oil supply still goes into the engine. But reading the oil pressure before the actual engine is absolutely the highest pressure reading possible on the engine. It's also the worst place to read it from a technical point of view, it's better to read it after all the feeds have taken their share. But it worked for me.
Bob, I figure my video is going to be me bringing the bus to a rally and letting someone else take a picture of it! ;D Maybe this fall.
Brian
Brian, good for you!
Isn't it a great feeling after all this time and effort in the shop to start it and it runs nice and smooth and to see the oil pressure come up...
Somebody closer than me has to go take a video for us nuts.

They all read about 60 to 70 lbs when cold the oil is thick and temps are low so the oil won't pass through fast enough for the 50 lb relief valve on the block that dumps it back into the pan run it on the highway for a couple of hours you will be 50 lbs and around 10 at idle it is a DD lol
