BTW if possible find out oil consumption...worn valve guides do not show up on a compression or leakdown test unless they are very very worn.

Or one's oil tank is very, very full!

THIS is so correct. Make sure that during the PPI that the mechanic knows 993s and knows how to physically check the condition of the valves. Even though the 993 only has 28,000 miles on it I would still check.

Back in 2005 Steve Weiner-Rennsport Systems (RL Technical Advisor) posted......

.....the side-wiggle test is subjective and its requires someone with extensive experience to make a judgement about how much sideplay is OK and what constitutes too much. Fortunately or unfortunately, this is the only way I know of to make an assessment of valve guide wear aside from taking everything apart and measuring guide-to-stem clearances.

For me, the side-wiggle test has proven to be accurate in making a judgement about whether the guides need replacement but I've been doing this a LONG time,....

Like many other endeavors, a minimum level of competance is required for ANY PPI to be useful and valuable.

Thanks guys. Hopefully I'll be posting pics of a new ride here in the next week or so.
