HI Kevin,
Thanks for moving my post to the appropriate section.
Yes, I did read the post on the 408 sump removal. At that time I was under the impression I had the later Chrysler 318 engine, which I thought was fitted to some of the 409’s and all the 410’s.
I won’t bore members with the works I have been doing on the V8 engine but while waiting for parts to be delivered I read an excellent article on the SLJ website about checking timing chain wear on V8’s. So I thought I would do a quick check (any excuse to get back into the garage). The test took only minutes but what I found was very worrisome; I had in excess of 12.5 degrees “play” on the crank shaft due to wear or stretching of the timing chain. After removing the timing chain cover, timing chain and sprockets I realised when the time comes to replace the cover, to do the job properly it’s necessary to remove the crank case sump to fit the gaskets correctly. It can be done without removing the sump but I would have probably ended up with an oil leak which would have only replaced the one I had before starting the job.
I have had difficulty in obtaining a timing chain and sprockets similar to the ones I removed because I was trying to obtain the equipment for the later Chrysler 318 engine (my 410 is 1967)
In fact I have subsequently been told that my timing gear is off the earlier 318’s built between 1957 and 1964. I am now waiting impatiently for their arrival from the USA; just hope it’s the correct one this time!
Finally, removing the sump on my 410: taking out the 18 bolts holding it in position was quite painless but it’s necessary to lower the sump and slide it forward slightly because the rear of the sump has a small lip just rear of the rubber semicircular gasket, the only way I could free the sump (without any force) was to remove the bolts holding the cover plate to the front of the bell housing BUT not the bolts to the starter motor; this allows a little wriggle room for the sump to clear the plate. The interference between the sump and the bell housing face plate was only about 1/16th of an inch. It wasn’t necessary to raise the engine or remove any other parts.
I don’t know if the sump on the 411 can be removed in the same way.
