It's time to get my 300SD engine back together. Some may remember I bought it on eBay a month ago with a broken timing chain. Can't see any valve damage, but it doesn't matter as the cam is broken in three pieces as well as two cam towers.

I've taken the head off and got a replacement from a friend (Thanks 300SD Sady!). I pulled the pin and put in a new chain slide rail. The replacement head is ready to put on. But first I want to install a block heater as this block does not have one. I purchased a 19mm allen key and used a 5 foot pipe to loosen the plug. A 1-13/16" socket and a 3/4" ratchet helped me get the heating element into the block. I replaced some of the coolant and verified that the element worked.

It was misting outside so I closed the hood for the night. Now for some deep thoughts and planning.

The chain is hanging out the driver side of the block and there is none on the other side of course. This means I can't roll in a new chain (even if it were timed correctly). My thoughts were to remove the oil pan and either thread a wire or chain down the banana rail and connect it to the end of the broken chain at the bottom of the pan by the crank gear. I could then turn the crank and bring out the new chain. I could alway loosen the chain and turn the crank until it get to TDC so that I could set then the cam timing.

Good? Well not quite as the IP is not timed at all!

I guess I'll have to take off the IP, but how do I time the gear for the IP?
