Thread: S1 Holden 186 smoke issues

1. hurt my back yest from lifting the damn hoist box on my own, though not that heavy did pull a muscle in my back so with caution today this happened... removal of the original engine, thanks for the heads up on those wheels realised the weight was on the front 4 wheels only, cheers for that

2. raised out of the engine bay with the rear bits bolted into position like the adaptor etc which is nice to know i can bolt them back onto the newer engine to fit into position (was thinking i would have to bolt the adaptor after it went in from the cabin side)

3. fully out, jeez first time using the hoist and it makes life so much easier - it was a breeze to do

4. side by side new vs old, just need to bolt on adaptor, flywheel, clutch etc onto the newer engine before fitting and a lick of paint for the sump before fitting

5. an empty engine bay waiting for the newer engine

both engine are on wheels to move about, might see if i can sell cheaply the old block or worth removing the pistons to keep them - not sure yet. another job done yay happy days

You just need to swap all the bits from the old motor to new ( flywheel & housing , spigot bush if different , engine mounts if different )
You will be able to use that hoist to lift the gear box out if necessary. That will save your back also.

1. day started off well, took off the two side engine mounts and fitted to 202 - job done

2. comparison of the flywheel, the LR one is larger then the smaller holden one, no problems there i can swap them over

3. next thing i noticed was the teeth on both flywheels, LR one has much larger seems more heavy duty teeth then the holden, easy can swap that over

4. next thing i noticed was the lower block extreme on one side had some surgery - thought no worries moving over to the 202 so no problems except...

5. this is the 202 one, its been cut off to allow the starter motor to fit through that hole when the adaptor housing is in its position - bugger moment. can or should i just get an angle grinder out and butcher like they did to make fit?

6. the 186 spigot hole is larger

7. the 202 spigot hole is smaller - 2nd bugger moment.

should have been an easy swap out but not that simple - what can i do? just pull out the spigot from the 202, not sure the 186 had one now!

Joe I would be replacing that Welch Plug while you can , will save pulling the motor out again if it leaks in a couple of years. The LR 1st motion shaft is larger in diameter than the Holden one. You will be able to get the spigots out by packing the hole full of grease then find something that is a neat fit in the hole then driving the drift in with a hammer , the grease should hydraulic it out. Can't help with weather to cut the lug on the Holden motor , never had a LR with a Holden red motor.

It looks like your old motor is missing the spigot bush you need to check the diameter of the hole & the diameter of the shaft , if the shaft is loose in the spigot it will brake the centre out of the clutch plate .

Something strange going on , every time I try to edit a post it ends up doing a double post , also when I click on edit post it adds all this strange gibble gobble which I have to delete.

I've never seen any other Holden installation with the block cut like that, nor had to do it when I fitted one myself or to one I removed from my latest - maybe the wrong starter or something?

As mentioned, use grease to hydraulic the old spigot bearing out - last time I did one, I uses a 1/2" extension with a rag wrapped around it - not ideal, nut got me out of trouble. If you can find something that's a closer fit, that would be preferable.

Agree it would pay to change the welch plugs while you are at this stage.

1. yes agree I have never seen or heard of the block being cut up - I'm beginning to think this adaptor housing is not the correct one for the holden engine conversion, but you see the starter blockage with the block in the pic (behind)

2. It pains me to cut up the block but in order to get this job done, I carefully started to cut away pieces of the block and re fit the starter till it cleared

3. more of the block cut (butchered) and cleaned up as much as possible to resemble original spec holden engine

4. adaptor housing now fits and allows starter to fit as well.

5. is this another spigot for the flywheel, seems like my old 186 had nothing (large hole), the newer 202 has a smaller spigot (unable to fit shaft from gearbox) and then there is another spigot in the flywheel. will need to take some more measurements on this

6. while i had the grinder cut away the side wall of the chassis radiator support now has a gap which will need welding next - allows water to drain freely away and not rely on the two smaller holes i had drilled previously for drainage.

I may leave alone the welsh plug for now - I need to sort out the spigot - i have seen videos of the grease method to pull out the spigot but saw another video using a bolt/nut which i tried today but did not work for me. so that will be next.
