User ID: 381742 United States11/12/2009 08:35 AM Report Abusive Post Report Copyright Violation | Ok, I'm down to the cylinders. I found a small tear in cylinder #5 from combustion chamber to coolant passage to exterior. Quoting: ºCRAPºLower Intake Manifold gaskets were shot as well, but thankfully no coolant in the oil :) Things are going great, everything labeled, the push rods are ordered correctly in a peg board like setup. Every wire is labeled with blue tape and everything was done to spec. Now here is the BIG QUESTION! The coolant passages for the Felpro Head Gaskets are much smaller then my block passages. Should I keep the passages smaller restricting coolant flow or should I cut them to shape perfectly? I don't understand why the gasket passages are pencil sized holes when the block has passages that are about 3-4 times larger in surface volume. Anyone with experience please chime in. Thanks Make sure your gasket is not backward. It's a common mistake and can make the vehicle run hot. Don't cut on a Felpro gasket, they are made to exact specifications.

Are you sure? Because I just read they were designed like that to promote coolant flow. Maybe there is some science behind the madness. I would think the coolant passages should be the same on the gasket as the head and block. I mean, everything matches except the coolant passages. It is the right gasket set, I'm sure of that. This really puzzles me. A part of me says, do it by the book and just put it in as is. Don't want to tear it down later if it causes problems cutting it to fit. Another part of me says, simple logic, the coolant will flow better with matching surface area. The system is bleed and under 15 PSI soo it won't stop any boil over as the pressure prevents that. And its a Pontiac and all GM 3100's run hot. I'm on the fence here. I need to know if anyone actually done this before and what the end results were. Has anyone here modified the head gasket as I question? How did it hold up? Thanks |

| Anonymous Coward (OP) User ID: 728223 United States11/12/2009 08:41 AM Report Abusive Post Report Copyright Violation | Get head crack and warp tested before you put it on. Quoting: Anonymous Coward 806478Well, I'm just trying to get by until spring to buy a better car. If there are cracks, I'm not going as far as to fix it. I'd rather just replace the head or swap the engine out for a 3.8L DOHC with charger and headers. But I doubt there are cracks anyways. Because I never red lined the engine temp, took great care of it. The engine was cleaned with seafoam in the crankcase and then flushed. Put in 100% synthetic with Lucas conditioner 50/50 mix. Coolant system is flushed often. The head gasket problem was caught really early. Absolutely no coolant in the oil. I'ds say the odds of there being a crack are low. Besides, the cost is there too. That is why I do this myself. Cost me just under $300 when a shop is around $1400-$1700. |

Quoting: BRIEF AND TO THE POINTI push it hard and it's 13 years old. Plus the cooling system was the orange crap that eats at the gasket material. GM is facing a large lawsuit over it but I'm third party owner with a 3100 from a Beretta so I doubt I can jump the suit. The coolant was flushed and swithed to green to avoid gasket issues. That is ok. The dexcool destroyed the gasket. Notice the problem was the smallest distance from chambet to coolant passage to exterior. The coolant passage was in the center of the damaged area. That is pretty much why its shot. No bent valves or pushrods. The drivetrain is in excellent shape. I do also suspect it was running a bit lean due to a small vacuum leak in the plenum gasket. Prevoius owner used black RTV w/o gasket and it had a miss. So the lean running probably encouraged the gaskets demise. I'm happy it was caught really early. Lesson learned cause I could be facing water in the bearings and that is really bad. Basically, I resolved the issues why the gasket blew. I probably was to vague in explaining that, sorry. |

In most of the cases I've seen the head gasket coolant ports to be approx 30%-60% the size of the coolant holes in the block and head. This is normal. Make sure head and block deck surfaces are perfectly clean. You can use a razor blade or scraper to carefully clean up the surfaces. I usually give them a cleaning with thinners also. Orientation of gasket is also important. It sounds like you are doing a fine job so far. |

Quoting: BRIEF AND TO THE POINTyup, I have a new water pump as well as a new radiator. My old radiator had a crack in the intake tank. Probably from over pressure. That is what led me to question the head gasket and said, fuck it, I'm going to replace it anyways. Thank God I did that. It was caught very early. And Dexcool is terrible stuff. I should have switched to green long ago. New pump and New radiator, and the block is going to be snaked to check for coolant blocks. New thermostat, coil packs, plugs, wires, fuel filter, oil filter, air filter, TPS, MAF, Fuel pump, Battery, ECT. Dielectric grease on all wire contacts. Engine grounds cleaned. I'm going to wrap my exhaust. Big time DIY fix up project before winter. |

It won't even scrath glass and I use seafoam as a degreaser/cleaner/lubricant to clean and polish the heads. I know a micro scratch can damage the gaskets from heat cycle expansion and contraction. So far the heads are very clean, degreased and ready to go. Just before I put it back together I'm going to soak the cylinder heads and other various componemts with seafoam so the start up will clean up a lot of carbon that is left. I am not scrubbing anything in the chamber. Keeping it perfectly clean. Thanks for the advice, I'm leaving the gaskets as is. You confirmed my hunch about the designers knowing what they were doing and it was designed that way for a good reason. |
