1600 dp heads

Postby vwlimoguy » Wed Aug 01, 2012 5:20 pm

Whats the latest rage these days? Is there a good local shop to rebuild my original german heads or is it better to buy new ones? I've done it both ways in the past with no problems either way but thought I'd check in see what the trend is. Its bee 7 yearts since my last engine build.

Sometimes rebuilds locally cost as much as new, depends on if your seats can be cut, or need new.

What about other local machining? I need my case align bored and thrust cut, maybe regrind the crank too.

Darrels, Larry, Bethany (roger) not in any particular order. Crank polishing/turning nobody does it themself. Mason will chime in about the crank shop.

Mikes machine on 59th will grind a crank idk how much he charges. Its through the red gate behind the pawn shop. I have also heard of people using weisco in town. I would talk to Rickey from sandsation he has stock reground cranks in stock usually. Might be a better option since most shops charge a setup fee.

I was in Mike's Machine shop about a month ago....he did some head work
for me for: my daughter's Suzuki Forenza, the timing belt had broke and
bent 10 of the 16 valves. One just has to love an interference engine.
He stated that he does the VW crankshaft regrinds for Bethany Imports, so I guess
if you get an exchange crank from B.I. you are getting one of his regrinds.

Most valve jobs on stock dual port heads do not involve the replacing of the seats,
but just machining the existing seats, unless one wants to modify with bigger
valves. The exhaust guides are checked and usually replaced. The intakes guides
seldom ever wear to the point of replacement.....if the intake guides are worn....to
the point of replacement.....those heads have too many miles on them....and I would
suggest not messing with.
Always check for cracks....and if cracked in the spark plug area running to one of the seats....
junk-em ....not worth messing with....
also one should always check the mating surface where the cylinder meets to the head
