water pump, head bolts on 90 accord EX
Hey,
We just took this 90 accord apart, a burned valve from leaking valve stem seals. It is the F22A4 motor with 200k on it. The compression numbers besides the blown cylinder were consistent. The head is in the shop now. In the meantime I bought a Felpro gasket set, Gates timing kit, various tune up components. However, I am stuck on a few things. - The head bolts that came out look like standard hardened steel bolts. One of them is much longer than the others. The torque specification is 3 stage, not a torque + angle. Are these head bolts reusable (i.e. after cleaning up the threads with a die) or do I need to buy new ones? - I have a choice of a reman Cardone brand water pump, or a NEW "Master" brand water pump at the parts stores. Should I go cheap or play it safe and get the OEM pump, and if OEM where can I get a good price on it? - What do I call the o-rings that keep oil out of the spark plug holes from the valve cover? The parts stores have no idea what I am talking about or how to look them up. - There were not oil pressure problems. Should I worry about a new oil pump or leave well enough alone? |

I like to use a 3/8" drive model since the torque specs are closer to the midrange of the accuracy of these wrenches. Using a 1/2" drive model puts the torque specs much too low on the accuracy range of the wrench. Reusing the head bolts is usually not a problem. Do not run a die over the bolt threads but clean them with a standard parts cleaner style brush and solvent. I like to run a tap through the threads in the bolt holes after soaking them with carburetor cleaner (be absolutely, with out any doubt what-so-ever, certain that you're using the correct sized tap or it will be a bad day afterwards). The bolt holes should be blown out with compressed air afterwards and it may take a couple of cleaning cycles (with carb clean only) to get all of the gunk out. Be sure to keep any gunk from getting in the cylinders or meticulously clean it up afterwards. I like to lube the bolt threads with a thin oil such as LPS #1 and put motor oil between the head bolt and its washer. > - I have a choice of a reman Cardone brand water pump, or a NEW "Master" > brand water pump at the parts stores.

This is just my opinion, but a water pump is too important for these cars to gamble with a rebuilt unit since it's driven by the timing belt. Buy the new OEM unit. Check the prices at online Honda dealers such as http://www.hondaautomotiveparts.com and http://www.slhonda.com. > - What do I call the o-rings that keep oil out of the spark plug holes > from the valve cover?

If the parts counter people don't know what you're talking about with such a basic part, then you should switch to people who are more familiar with Hondas. > - There were not oil pressure problems.

Actually, according to this:
http://www.aa1car.com/library/ar396.htm I would be better off with the aftermarket gasket on a MLS application, because the OEM gasket requires an OEM surface finish which is difficult to obtain. Felpro says they have some kind of sealant on their gaskets that is supposed to tolerate non-OEM surface finish better. |

All the exhaust valves were pretty bad. The way it was explained to me
is that the oil leaking down the valve stem accumulates on the seat eventually preventing the valves from completely transferring heat to the seat. Is that wrong? All the "hoping" is because I had to use a new machine shop due to the location. I think I will give them a call and remind them not to mess with the finish on it. The gasket was not blown so there seems little reason to mess with it especially given the risk. |

Oh, and am I off the mark, or is this motor a strange case - where you
have an open deck motor, but the head bolts are not torque-to-yield type meaning they can be reused? |

OK, I talked to the guy and made sure he isn't going to mess with the
surface. He said it was true anyway so there's no reason to do anything with it. On the same page finally! |
