Thanks insite for the great info!

quick update. car is running great; it's a real rocket. i've ordered an accusump that i'll be installing in a week or two. i finally feel comfortable that i've shaken the car down enough to hit the track. april 11th is the day. i am going to set the car up EXACTLY the same as the day i blew the engine:

same weight, tires, alignment, etc.

the goal is to isolate the time difference ONLY from the engine. also, i'm a little rusty. it's been almost 2yrs since i hit the track. my bogey time is 1:11.6. anything below this is all engine. obviously i'll tape a session or two.

one other note: when i drilled out the exhaust manifold bolts, i meant to post a link to the centering tool i used to get the pilot holes so nice. this thing is AWESOME. it's called the quikcenter and i highly recommend it:

until next time.

how does that product work exactly?

the M96 motors, especially the earlier ones, can suffer from oil starvation in track conditions. it has to do with sump depth, poorly designed sump baffles, and inadequate oil scavenging in the heads. each head has a scavenge pump, but it's located at one end of th car. this means that if you're accelerating or deccelerating while in a sustained high-g corner, it's possible for oil to pool in the cylinder head AWAY from the scavenge pump, running the sump dry & killing the engine.

there is an easy way to address ALL of these problems. the accusump looks like a bomb in your trunk. it's' a big cylinder that holds two quarts of oil under pressure. when the oil pressure in the engine is greater than that in the accusump oil flows into the accusump. if the engine oil pressure drops, the accusump will make up the difference by feeding oil into the motor until pressure returns. it makes sure that, even in adverse high-g driving conditions, there is a steady supply of oil to the engine's wear surfaces.

Firstly, I want to apologize for not being clear. My question was not about the accusump (which seems to be a great product for the price compared to other oil starvation solutions) I was just curious how the qwikcenter tool works. I went to the site but it did not really spell out how it is used. Furthermore I will be changing out my headers within a week or so and it may be something I will need. Never-the-less, thanks for the info on the accusump your explanation clears up any questions I may have had on that particular piece of equipment. I do plan on getting one some-day but I will probably do a motor swap first.

P.S.

what other tools did you use for drilling out the broken bolts? for re-threading? and what bolts did you use afterwards anything special?

the quikcenter tool works multiple ways. first, purchase the version with the correct diameter and thread pitch for the bolt/stud you are drilling out.

if there is a portion of stud protruding from the surface, thread the quikcenter onto the stud. now it will guide your 1/8" pilot drill bit directly into the broken stud.

if the stud is broken off BELOW the surface, you can twist the insert until it goes into the fastener hole. now you can guide your pilot bit.

finally, if the stud is flush with the surface, they make a collar that you glue to the surrounding surface. the centering tool will fit into the collar and allow guided piloting.

the tool is great. my only complaint is that they're made of aluminum and are a bit soft. i had to do ten bolts & my quikcenter is pretty much toast. the good news is that it was eight whole bucks. it was a life saver.
