Default Valve Job pricing assist

My mechanic has spent the last two weeks soaking my SAI passages with carb cleaner etc. to little avail, and (at 141k miles) it looks like a top end job is in my near future. So time to research my options. My tech says it normally runs around $8k - But he'll do mine for around $6k. I recall reading about a well-known guy somewhere in the New England area that'll do it for $3K - which sounds perhaps too good to be true. Search function here is excruciatingly crap lately and I can't find any reference to it, but does anyone with a better memory than I recall info that fits that description? Any help (that might save me $3k) would be much appreciated!

Matt,

If I might add,.......

Having done a few of these,........ $6K is a good deal for a proper job. Naturally, labor rates vary widely so that needs to be factored but knowing what I know about this process, I get suspicious about what kind of a job is done for $3K.

JHMO, of course.

Exotech in Plaistow, NH (Mark Nadler) can knock it out for $3500~ assuming there are no other issues. He did my 993 which was VJD3's old car and if I'm not mistaken he did Vic's current 993. I have been delighted with the work that Mark has done for me. While location will not roll your socks up and down, he knows what he is doing. He's about a 2.5 hour drive from you and well worth the trip.

Thanks Trintony - I think you are right. I PMd Vic.

- Steve, I agree, $3k sounds too good to be good. My tech says it's a 40 hour job, which equals $3600+/- before paying for heads re-machining, new guides, rings, seals etc...

He said it would normally run $8k-9K but would do it for $6K because I am such a likeable guy As you know, my income is derived almost solely from the newspaper business so I am looking for the best deal I can squeeze without compromisng quality.

What is your oil consumption like?

You could try the bass guitar string method...

It's not bad...2-3k miles to a quart, but I have a few noisy valves, so I imagine oil consumption will gradually increase if I continue to drive without doing the top end.

Yes, he did his current.....

And how far from MD, since I may need it in few years? if I don't sell before..

One more vote for Mark Nadler and Exotech. It has been almost 5 years 12,000 miles. Cal smog test numbers are great. I think I had 27hrs labor. + parts.

2-3K to a quart is very good. Normally, we don't recommend a top-end until oil consumption reaches 800 miles/qt.

I would investigate the source of the valve noise and see if its due to lifters, worn rockers, or valve guides before I did anything.

I'd also recommend a leakdown test before committing to installing new rings. You may only need guides and perhaps, exhaust valves.

How do you suggest measuring oil consumption when it is also tracked? I don't get more than about 500 miles between track days these days, so oil consumption is a bit tricky to measure. I'm at almost 130k mi and regularly DE, so starting to wonder...

Steve, I have a CEL with blocked SAI ports, so can't get past emissions testing, otherwise I'd leave well alone until the car started using more oil. I have replaced exhaust lifters, so I'm sure the noise I'm hearing is exhaust guides. I have a few oil leaks, so was thinking of maybe dropping the engine anyway for some resealing work...And you know the drill: if it's sitting on the bench anyway...

Otherwise, the car runs exquisitely.

Sounds like pretty good advice. A few questions to help me learn about our beloved 993 engines...If your valve guides cause noise would your oil consumption not be horrible with that kind of clearance? Out of curiosity, how do 993 engines take to new rings without honing? My understanding is that the cylinders can't be re-honed due to their hardness. I might be misguided here (no pun intended) Just curious and trying to learn a few things.

Hi Matt,

Understood about the SAI passages. We enlarge these during head servicing to help prevent recurrance (along with using our own guides).

Be careful about installing new rings as oftentimes, they fail to seat properly in original cylinders due to improper preparation and cylinder ovality. Thats why I recommended a leakdown to see if yours are still good.

As I recall, you're not going to see the oil consumption that you would if it were the intake guides. IMHO, echoing what Steve W. said, your engine doesn't seem to be that far gone. I'd certainly try the guitar string/rotor-rooter method on the SAI system b4 committing to an engine pull.
