What do I do when a helicoil is sticking a little bit out of the hole where I need to stick a stud in? How do I get it back in? This is on the exhaust port of a head.

Can't anyone reply. I am talking to myself on this thread. I have to put the exhaust back on tomorrow!!!!!!!!!!!!!!!!!!!!!

I got pictures of the crack. They are a little blurry. The crack is on the right side of the ridge. It crossed over the ridge and then goes down the sides of the ridge.

I need to know if I should be worried about this crack. I need to know if there is anything I can do to fix or slow it down before I put the exhaust back on. And I need to know how long I will be able to drive on this head.
This crack is on the exhaust port of a generation 2 turbo side head.
I hate cracks:boohoo:

the crack is on the ridge, but it is not on the center of the ridge. Its on the end of the ridge. The heads are generation 2.

I pulled one of the studs out and the crossover pipe finally came out. As I was looking with my flashlight inside the exhaust port of the turbo side head I noticed a small hair line crack. Does this mean I will be shopping for a new head in the future? Is this crack in one of those places where it is okay to be? I did not see any coolant, so could this mean that the crack is too small to be a problem yet? The car was running great before I started working on it. Is there anything I can do to fix this? Hoe long could I run on this head?
What should I use to clean out the exhaust port? I was thinking of using carb cleaner.

Alright, I finally got the engine up a couple of inches. I just kept jacking it up at the oil pan. The car moved up with the engine until a certain point and then the engine started to move up with out the rest of the car attached.
Now I am trying to get the crossover pipe free from the studs. The pipe is so warped that it is rubbing up against one of the studs on the driver side head. I might have to remove that stud. Well back to work...

I am trying to drop my front exhaust (crossover) pipe enough to clear the studs so that I can replace my blown exhaust manifold gaskets. I pulled off the the downpipe and removed all the nuts off of the studs that hold the crossover pipe on. Now I am trying to get the crossover pipe to drop, but it won't. The turbo is still resting on the crossover pipe. I didn't want to deal with removing the turbo completely. I was thinking that if I raise the engine 2 inches, then I might be able to jiggle the crossover pipe loose. I loosened the pitching stopper and took off the two nuts that hold the front engine mounts to the crossmember. Then I placed a floor jack with a block of wood under the engine's oil pan and started jacking. My problem is that the engine does not want to move up without the rest of the car. What do I do? What else is holding the engine with transmission to the rest of the car? Do I have to loosen the transmission mounts? Will I be able to drop the crossover pipe without removing the turbo?

I have been running NGK iridium spark plugs for a couple of weeks in my EA82Turbo. They work great, but I am not sure how much they benefit because at the same time I put them in I also put in a MSD Blaster Coil, Magnecor 8.5mm wires, and I gapped the plugs to 0.050 inches. I ran bosch platinums before the iridiums. My car improved dramatically after I did all this. It ran smoother and it felt much more responsive.

Check the fuses. If the fuse(s) for the blower is good, then check the relay. There are four relays above the fuse box. One of those is for the blower. I had the same problem and the culprit turned out to be the relay. If the fuses and relay are good, then the problem may be the switch.

I just took another smog test today. It failed again. This time I got 197ppm for the HC at idle. Back in April I got 1011ppm for the HC at idle. So at least it improved. I need to have 120ppm of HC or less to pass. My car passes on all the other tests. I replaced the oxygen sensor, spark plugs, ignition coil, spark plug wires, fuel filter, oil, oil filter, air filter, thermostat. PCV is new since December of 2002. I put some Redline fuel system cleaner in. I checked the EGR and it is good. The only thing I think I have not replaced is the cat. What am I missing? I think I am ready to give in and use something else besides 91 octane gasoline. So is methanol or ethanol too corrosive? Which should I use? Will it ruin anything such as my cat, new O2 sensor, or EGR. Where do I get it? What other options do I have????????????????
BTW, this is for my sube in my signature.
-
If it is a turbo, than you want to go with a 2.5 inch (not a 2 inch) diameter exhaust.
-
Is it more likely for a car to pass a smog test with gas of a low octane level such as 87 or of a high octane level such as 91? Or does it even matter?
-
I think I have an idea on how I am going to gap them. I just want to make sure I don't ruin them by doing something wrong. I was just thinking of using a pair of needle nose pliers to bend the tip of the plug and use a thickness gauge to get the gaps set to the correct gap thickness. Is there anything wrong with using needle nose pliers? How fragile are the tips of spark plugs anyways? I am worried about breaking off the tips.

looking good!!!!!!!! This is way more advanced than the old board, yet I already got the hang of it. Thanks to everyone.
Helicoil Thread sticking out of hole

I guess it would be the top of the hole. Most of the coil is in the hole. The tang is not there. I never dealt with helicoils before.
