mbs2013 Posted April 25, 2021 Author Report Share Posted April 25, 2021 Yeah the car was part restored by the previous, previous owner and then most recently stored in a gazebo I think. Only had a brief look at it today. Getting behind it is ok, but I can’t get anything in a position to put force behind it because of the bulkhead Link to comment Share on other sites More sharing options...
Badwolf Posted April 25, 2021 Report Share Posted April 25, 2021 I was thinking of renewing my core plugs due to a suspicious dribble of water on the floor. After this, maybe I'll just chuck in a can of Wynn's rad seal for the moment. Link to comment Share on other sites More sharing options...
Colin Lindsay Posted April 25, 2021 Report Share Posted April 25, 2021 They should come out easily enough; I've done both Herald engines recently and they were a doddle, both cup and dished type, although I did use the seal puller tool pictured on the last page, plus a good hefty screwdriver.

PeteH Posted April 26, 2021 Report Share Posted April 26, 2021 Core plugs are not something I`ve had a lot to do with, I think the last was on Dad`s 1948? Hillman. Looking at the photo`s what you need is leverage. If you have a long(ish) "sacrifical" screwdriver I would be inclined to weld a bolt or rod across the driver close to the Tip (say about 1"?) that would improve the "purchase"?. Once you "crack" the join, it should come easy. Pete Link to comment Share on other sites More sharing options...
mbs2013 Posted May 12, 2021 Author Report Share Posted May 12, 2021 Good news! I've finally got the plug out. It took a lot of chiseling (and a now broken chisel) but it started to give at the bottom which forced the top to come loose. It was then easy the remove. New one now in place but haven't had chance to check the seal as I've got to put the radiator back in first. Will be one for the weekend I think. Thank-you everyone for your advice. 2 Link to comment Share on other sites More sharing options...

johny Posted May 12, 2021 Report Share Posted May 12, 2021 Good news but, and sorry to be a right pain, wont the new one go in just a little bit more? I can see its been difficult as space is tight but if the plug edge was a mm inside the hole it would be perfect. Could a socket that fits snuggly inside the plug be used to push it a bit further...

Colin Lindsay Posted May 12, 2021 Report Share Posted May 12, 2021 Edges are a bit raggedy on that one, it's been battered into place. As Johnny says a good socket of the correct size will push it into the block / head or else put a flat metal face over it and hammer that. Looks neater!

I'll give it a go. I had read that one then completely forgot so went with the piece of wood. It was a very tight fit to get it in that far, thus the raggedy edges.

johny Posted May 12, 2021 Report Share Posted May 12, 2021 Ive even been known to use a sissor jack in a situation like that - pushing off the bulkhead with a packer to apply a steady pressure to the socket😵 1 Link to comment Share on other sites More sharing options...

johny Posted May 13, 2021 Report Share Posted May 13, 2021 I do envy those programmes on the telly though where a new engine (LS400?) comes out of a crate or they have it mounted on a rotating stand and bolt on the pristine supercharger - maybe one day...

You'll need to clean up those ragged edges before trying to tap it further in. Link to comment Share on other sites More sharing options...
Pete Lewis Posted May 13, 2021 Report Share Posted May 13, 2021 to me thats in far enough to do its job its not far off flush the working faces are well engaged in the head bore i would sooner you paint up the rocker cover than struggle to achieve little more with the core plug pete 1 Link to comment Share on other sites More sharing options...

Same head on my late 1200, and the core plug looks to fit tight to the edge and no further in. The smaller one goes back further; you can see the lip round it.
