Thats kind of the plan... but its a pain... Mostly because i have to remove the exhaust system... And rent a puller again to get the pulley off.... Also I'll have to open up 2 of the holes to allow the 3/8 studs to fit... Previous issue with pulled threads... 2 are 8mm 2 are 3/8 now... Quote Link to comment
Crashtd420 Posted July 23, 2025 Author Report Share Posted July 23, 2025 One thought I had was is the gasket what's screwing me.... This was supposed to be a full flow pump with in and out coming from the cover... I capped it with a cover plate but used a gasket like this.... Then I got to thinking the pump came with a gasket like this. Which seals that 1 hole.... The outlet is the left side lower cavity and return in is the upper hole.... Without thats sealed am I just recirculating in the pump or should that not matter? Either way I'll probably swap pumps... seems the most logical and I have it... Quote Link to comment
Crashtd420 Posted July 23, 2025 Author Report Share Posted July 23, 2025 Well I think I'm a fucking idiot..... Actually I hope I am because if I am right the fix is possible... The pump I have installed is a full flow pump.... which means oil leaves the pump from the large chamber and returns to that hole.... then out the side.... A stock pump oil exits the left side of the large cavity.... I'm guessing when I get home there will be a through hole from the side of the pump.... Since the full flow pump is already fitted I might just plug the top hole and drill the side hole through.... Fingers crossed Quote Link to comment
Crashtd420 Posted July 23, 2025 Author Report Share Posted July 23, 2025 So it was the pump..... See the top hole but no hole inside.... The other pump.... Turned out to be easier to oversize 2 mounting holes to fit the 3/8 studs vs drilling the cross hole.... Now I have good oil pressure, thank God I didn't ruin the wife's engine .... 1 Quote Link to comment
Crashtd420 Posted July 23, 2025 Author Report Share Posted July 23, 2025 And a successful test drive has been completed.... System functioned as I originally intended .... definitely removes a lot more heat at idle now..... Just need to double check the oil level and the wife is back in the driver seat.... 2 Quote Link to comment

Having a Type 1 engine didn't help my situation... most of my issues came from being confused, atleast now I know what I am dealing with... alot of head aches but only wasted $75 in the end.... 1 Quote Link to comment
Crashtd420 Posted September 15, 2025 Author Report Share Posted September 15, 2025 I feel bad for the wife, right now her bus is down again for repairs and she's been killing it driving it around town... but it just won't hold an idle and its been studdering and stalling out... I also could never get the fast idle to work... I decided to just put a new carburetor on, it has currently one of the knock off weber.. I got one for the datsun and its been fine so I just got the same thing she had, just new... Hopefully thats all it is.... Since she still has points I also got her a pertronix distributor, its was only a couple dollars more vs the conversion vs a points tune up (I was surprised the cost for just a cap rotor and points)... plus i get a fresh distributor, a new cap and rotor and luckily I had the 3 ohm coil i needed for it. Plugs were new as of winter plus I made some new higher quality plug wires... Fingers crossed the weekend goes well and she'll be driving the bus again soon... Quote Link to comment
Crashtd420 Posted September 15, 2025 Author Report Share Posted September 15, 2025 Well thankfully I had a successful weekend... Weber worked out just fine... And I can now set the fast idle, 3 pumps of the pedal turn the key and it started. But the damn thing still stalled out after about 30 seconds of smooth idling .... I needed a better idle to set the distributor, so I felt i was still doing good.. Got the distributor in and i couldn't get it to start now... walked a way, came back and double checked the firing order and 3 and 4 were reversed... Corrected that and it fired right up and idled as it should.... Even this morning 55 degrees out... 3 pumps, turned key, and it was 1800 rpm... quick tap it dropped to idle.... I called it a win.... She was able to drive it to work this morning... 4 Quote Link to comment
Crashtd420 Posted May 25 Author Report Share Posted May 25 The wife has been enjoying the bus already, driving it to work just about every day lately.... Ended up installing a basic temperature gauge for her oil... just so she has an idea of her actual operating temp.. She was complaining it wasn't running good on very cold mornings... which is true, but she couldn't judge how long to warm it up till it would run smooth... so the gauge helps her know... Also came across a VDO tachometer that fit the blank in her dash. I had some cheap 2" one stuck to the steering column which I never liked... This is much better and same brand as the speedometer... 2 Quote Link to comment
