| From Byrant 6/11/03: I have a 91 2.0 Si Prelude my timing belt popped. The mechanic told me that I had bent valves. The timing belt popped while I was going about 10mph. Is it possible for me to have bent valves??? It does run funny now b/c I had the belt replaced anyway with the chance of possibly fixing it one day, but it doesn't leak a drop of oil. Could I possibly take off the head and detect the bent valves??? And if detected, could I even replace them myself. I'm no ASE mechanic, but i've done a lotta work to the prelude and hate to let her go to waste. HELP!!! Reply from John 6/13/03: Bryant, This is John from Suitor's Garage. My brother asked me to address a question about your Honda. As you probably know my stepson had some bent valves in his honda and we tore it down at our garage. I believe the same thing happened to his car that happened to yours. I think the previous owner neglected to do the most important maintenance needed other than oil changes....replace the timing belt.....when the belt broke it was fixed leaving bent valves. I could see the marks on the pistons where the valves made contact. It ran pretty good considering the damage overlooked. Eventually the bent valves wore the valve guides and seals. His car ran alot of miles with bent valves, I told him if it was mine I would have lived with the oil consumption but he wanted it fixed right. Whenever you open an engine be prepared to rebuild the whole thing and hope you can get by with less. It's alot of work to do it all twice so do anything it needs while it's apart ... We found quite a ridge on his cylinder walls but not bad enough to bore. I got away with honing it and put new rings and bearings in it while I was there. I wouldn't suggest doing the valves yourself. I had it done at a Napa machine shop. Here is a rundown of about what the parts cost. Get a good manual ... $20 Machine work ... $300 Head gasket set ... $125 (this will give you all the gaskets you need except for the oil pan) Timing belt ... $30 (always replace this if you have it off!) Bearings ... $25 Rings ... $50 Oil pan gasket ... $15 These prices are about what I paid but they should be close. Make sure that you can tie up a garage for awhile, it's a pretty big job and you cannot rush it. Good luck and keep us posted, John |
