Thank you all for the info. at this time I can't get the engine out. I don't have a hoist, but I did drain the oil and remove the oil level sensor. I was able to retrieve more of the railing. The attached photo is only about half of what I got out. None of the railing was curved, so only the driver side was destroyed. I flushed the pan with several quarts of oil after running compressed air from the top cam shaft oil rail. Changed the oil and cranked it over with the valve cover off to check for function and peek down at the rear timing cover at the chain......huge mistake I nearly lost about a quart of oil spraying all over the engine bay and all over the exhaust. I properly buttoned everything back up and checked the actual pressure gauge this time and it's idling at 2.5 bar cold and drops down to about 1 -1.5 bar 80C. Pressure jumps up to 3 bar when I give it gas. I have a few m103 engines sitting around and was able to pull the cover off of one to get an idea of how it works. I removed the guide rails and it appears that as long as the chain has proper tension from the tensioner there isn't any issue with the chain flopping around. At any rate, I'm going to shop around for a hoist so I can lift the engine and refit new railings in. Looks like I'll be swapping out this 2.6 for the 3.0L sooner than I thought. About 515k miles currently on the 2.6L
