Early locally built Crowns had Holden banjos in a different housing (4 link) and were F@4D pattern

If my sad old memory is correct?

The locally assembled ones did. It was the fully imported ones I was referring to.

Jumped out of top twice heading down Hume Freeway. Second time started popping out carb and missing. Tappet noise at rear of engine. No apparent signs of blown head gasket an dissy looks ok too. Thinking a tappet let go or cam lobe maybe.

Ooooh, Clay, does not sound good.
20 odd Years ago, 186 engine, i had similar popping out of carb - under load, was worn valve guide.
I ended up replacing the head (exchange) on a Sunday for work Monday. As the car was my daily.

Bumpa T Bumpa was the local goto, to get an exchange Yella Terra head. LOL

Clay. This might be better! Looks like a Saginaw or “T10” 3spd maybe?

All good just a busted exhaust tappet. Back pushrod still not turning. Fan belt loose again. One push rod wasn't oiling the rockers, not the one that broke. Bit blocked so replaced with a spare. Now oiling. Back on the road 200km closer to home, and 14 days self isolation.

Don't know that would bolt to Holden six Byron?

The whole engine and box I meant! These were used in HD-HR in South African Holden. Not sure what box though.

[claysummers]

Reckon the blocks are too long to fit without moving firewall back and radiator forward. Holden 7 bearing straight six fits just. Thinking about trimatic. Meanwhile will beef up a crash box and go easy on the pedals.

Poor crunch box didn't like the new grunty donk
Whats your next box option ?
Was your fuel pump new?
Did you put sealant on the fuel pump mounting bolts?
Had pumps leak oil out the bolt threads & from worn pivot pins.
Hopefully a simple fix & not requiring pulling the sump!

Sorry missed this Trev.
No didn’t put sealant on the bolts. I recoed the pump. Had to reuse the pivot plugs after peening out. Used sealant on them. Kit had no plugs or pivot and wasn’t cheap. May go China pump as I see a few on cars lately. Though will make sure what the leak is. Still could be sump but pretty suss where it is. It’s all coming out so will soon see.

They fit in HR, they were used from some time in 1967, but as you say an FE-EJ has a little less room as the engine sits back a fair bit in those. I can't find engine bay photos but here is a HT. You can see it is longer and needs a skinnier shroud but could work with electric fans in an FE-EJ. Personally I'd probably not bother, if you wanted more than 202ci fit a 283 or 307 with alloy heads. Easy fitment into HD-HR and probably with a Trimatic (easy done today with available bellhousings). A mate and I trial fitted a 308 in an FC van once, just needed minor work on the firewall seam to make it fit on HR engine mounts. Lots more frigging around for the gearbox tunnel than it was worth though. I'd still love to try a 292 in a lighter Holden though, like a cab-chassis with alloy tray or a HK-HG ute. I had a guy willing to give me a running 292 at one stage to try in my HZ Overlander as the 308 lacked torque for towing, but never bothered as a 454 was actually easier to fit with available bits than the 292 was. Still have the 454 but no Overlander anymore.

Chuck one in an LC LJ would be best power to weight but they’re overpriced……………

Horrid to sit in though, legs one way and arms the other! A 292 with compression upped, better cam and an aftermarket modified head with a Quadrajet and HEI would be a nice engine in a HJ cab-chassis, with a 4sp auto behind it.

What valve lash do others run on their adjustable hydraulic lifters?

I have always set a clean sliding 0.004” on a warm engine. Over tighten with gauge inserted, then back off until it pulls out cleanly.
I use 4thou because I don’t have a 5 in my set. Discussing with a mate the other day, he runs them with slight pre-load. No gauge. Just takes out any lash, then tightens 1/8th turn. He says hydraulic lifters should be slightly compressed. I can’t see how he can be sure he isn’t over compressing them (other than exhaust note), leading to potential for burnt valves.

Clay, this is from my EH Factory workshop manual. Hydraulic Lash Adjustment.

Intitial "Zero lash" adjustment before doing the running adjustment, from fitting a new hydraulic lifter.
1. Is to wind a rocker nut down to just take out any lash, "Zero lash" between rocker arm and valve stem tip.
2. Then turn the rocker arm nut down a further 1/2 turn to compress the lifter piston to a midway position.
At this point I would rotate the engine around by hand to rule out any interference of valve to pistons , to be on the safe side.

3. Then start the engine, let engine get to operating temp, all lifters will fill with oil....then do the engine running adjustment procedure as pictured.

Hope this helps

Thanks Jaso. I wonder where I got the 0.005” clearance spec. Either Gregory’s or confusing with grey motor, but I remember doing this on my HK 186 around 1981

What the hell is (a) going to do? Thats pretty funny - how do you install a gasket with no rocker cover and expect it to
keep the oil under control?

I do it the way they description of the clattering part, quarter of a turn tighter down past that, even a half.
Heard differing opinions about how much, but don't think it matters, really. Greys are solids as you would know, 8 and
12 thou lash. Hydraulics don't want any lash clearance

Congrats on getting this far - motor got you home from your trip away in one piece, you must be doing something right

Bloody 6cyl’s

I actually bought a South African HR to HX Chevrolet style 6cyl to Aussie 3/4spd bellhousing last week. It popped up on Gumtree in South Australia. Seller was really nice to post it to me. Pretty sure it’s to suit Chev to 6cyl box, the ones Dellow and CRS sell are Chev to V8 Aussie box so it all ends up longer.

Those mighty dynotech cams - the fuel pump cams are just too wild

I too lost a fuel pump spring in the sump of my XU.
No amount of fishing with my flexi magnetic pickup tool could retrieve it via the fuel pump hole.

So left it in there until the engine had to come out one day...

Sh!!!!t happens.

[S pack]

My brother lost the fuel pump spring and the arm on his 186.

The parts were floating around in the sump for years and never caused any problems.

[claysummers]

Thanks for the anecdotes.
