Question: Cost of bent valves
I am wondering how much does it cost to repair bent valves? Ballpark range
also what other "implications" that a broken belt can bring?
I am asking because there is this for sale
http://sandiego.craigslist.org/csd/cto/3693589339.html
I am seeing it as an option being it is local, the exterior and interior looks pretty good and it is the year that I want.
The two bad things is that it looks like an automatic from the blurry pictures (looking for a manual), bent valves and any unknown damage from the belt.
I requested more pictures via email, so not much info on the extent of the damage (it was posted not too long ago)

None running cars you do not KNOW if the trans works, A/C works so you could spend thousands fixing the engine only to learn it needs a trans, radiator and $1,000 of A/C work. Hardly worth the risk. Bottom feeding has risks as sometimes you eat ****....

Just the engine block? I want an entire car and it has to be a 1986 version too. So tell me more, what is this sale you are talking about in detail?
Well I am at least forcing myself to look at only 1986 models now, but the more I post here and ask questions the more knowledgble I become.
So far I had been reading the 928 FAQ on the rennlist front page, and the important fixes like the fuel tubes.
I can wait.. I am just itching for a 928 (and even after I buy one, it wont be drivable until all past due preventative maintance is done)
If I see any sales ill be posting for advice here.

Yep, its worth the wait; And James, your quote about bottom feeding is true & priceless, I hope its ok that I quote you on occasion!
btw eijun, you just missed out on the very nice 86.5 that I posted fs here a year ago that had 63k on it, 20+ yrs of one owner, & an original Meteor Metallic paint job that had anyone who saw it comment that it looked new. I just helped the owner connect with a buyer. A buyer whom I helped find & buy THREE pristine 928s all at once, sight unseen,(including a '95 5 spd!) The guy's a car collector who always wanted a 928, so he just couldn't say no with each shark I brought to his attention! We should all be so fortunate with our love of Sharks, & never lose that passion! So take a deep breath & keep looking eijun, you'll know when you find the right Shark for you!

Had to laugh at the title: What is the cost of bent valves".
Bent valves are really cheap. Most people will give them away after they've spent lots of $$$ putting straight ones in the engine!!

And now for something completely different.
I'm mostly a bottom feeder. I've bought cars just like this before, at rock bottom prices. At best, your looking at a double head rebuild, and then the timing belt and water pump job. This is OFTEN not the case with bottom feeder cars. But - it could be.
More likely; The engine will come out, you'll do the needed job with the heads, and TB and WP. Then, you'll clean it completely, put in a new oil pan gasket maybe new rod bearing, and most if not all of the soft rubber lines on the engine. Install it in the car, and have a running car. Which will most often need plenty of electrical work, AC refresh, some suspension work, and maybe a bit of brakes or even trans.
Questions you have to ask yourself: Are you willing to commit to doing 90% of the work yourself? Do you have the garage space and time? Materials alone for the valve/engine work is going to be > $2k with machine shop rates, what can you find that's running for $5k in the same market?
Bottom feeding pretty much only works on cars that have a high residual value once finished. The 86 928 does not meet that definition, so prepare to be upside down on your investment even if you do all the work yourself. If you can see that in your future, offer $1200 and settle on $1500, tow it home and have at it. If you don't want to do the work yourself, I know an independent mech in SD that will work on it for you at pretty decent rates.

I'm currently doing a similar project. Mine had a cracked head. So I bought a replacement motor from 928int. But while the motor is out there is so much more you need to do. Like reseal it for starts. And it goes from there. You just keep finding things. I'm afraid to ad up receipts. I'm roughly in for an additional 8 to 10 over the cost of the car. And i'm not done yet. I'm having a good time, but it's not cheap.
