It did have a ticking noise sometimes in park and neutral. It would go away when you put it in gear. I checked it a while back with the stethoscope and decided it was coming from the bellhousing area. All of the fasteners were tight, so I decided to monitor it for a while and see if it was developing a crack in the flywheel.

I never checked the vacuum pump because there was no noise from the front of the motor. Shouldn't this one have the pump with the splined drive instead of the roller? I was thinking that the splined drive wasn't as prone to failure.

I may go ahead and get a tag for the orange porsche. It needs to be driven and gets twenty something mpg. The fuel savings could pay for the tag and insurance if I have to drive much in the next few days.

suggesting that your vac pump did the deal. i dont know if they are the same or not.

It looks like the guide for the tensioner caused my problems (I think). It is broken at the pivot point. The guides have a lot of wear that was not evident when the timing chain was in place. Or maybe I didn't look close enough when I adjusted the valves this spring.

I've got good news! The leakdown test (yeah, it was the low tech method with a blow gun) show that it did NOT bend any valves.

Tom, I didn't know for sure which style of vacuum pump was on this car until today (it has the splined drive, no roller to break). When you mentioned your problem, I developed a bad mental picture of what all could be damaged on the silver car. Thank you for accidentally prompting me to check the vacuum pump. It would be a shame to get it back together only to have it break another cam because I didn't look at something that I should have.

I am in a much better state of mind today knowing that both cars will be back on the road soon.

to be a help even if it is accidental.
