Just two quick questions.
Tomorrow I am planning on adjusting the valve clearance on my 93 Accord (1st time doing something like this but working on cars for 10 yrs is something I finally need to get under my belt, plus looks easy). I got all the tools ready, I just didnt check on the crankshaft pulley bolt size.
My question is does anyone know off hand what size socket I will need for the crankshaft pulley to spin the engine? Also would a 3/8" ratchet (long handled) with extentions be enough or do I need a 1/2" ratchet with 1/2" extensions?
Thank you

 

19mm, yes if you have the plugs out the 3/8 will work.

 

poorman212-thanx, I saw that on a youtube video about takin the plugs out that it made it easier, just wondering before I head out to the driveway to undertake the job.
Have u ever done it & is it as easy as it looks? I know takin it slow is the best way and know the feel of the feeler gauge is important and I hav experience w/ them at my full time job (machinist).
Thanx again for the quick reply.

 

How do you adjust the valve clearance on a 1993 accord

See if this will help you Do IT!

 

Ang has you going. Yes, only key thing is that the engine is "cold". From there just follow the directions/marks/cyls......don't take this wrong, my 17 yr just did his on the 89. I watched and only stepped in to be sure he knew what "drag" on the feeler gauge felt like. After two cyl, he had it down.

 

thanx for the help. i did it yesterday and all went well. The valves werent off much at all just a few adjustments here and there. Engine doesnt seem to run any different. Should there be a dramatic difference?

 

There should not be a dramatic difference.

 

The valves would have to be rattling like crazy to affect performance. I checked a 1990 w/ over 200K miles and found all very close to spec. Same on 94 Accord w/ similar mileage.

I've seen big claims for improvements from this maintenance, but am skeptical.

good luck

 

Texashonda - I wasnt really looking for performance or mileage improvements, I was mostly just doing some extra maintance to the car to keep it running better cuz I need it to be the best it can be.
Lately I have done, valve adjustment, egr port cleaning, cleaned out egr, iacv & ficv, changed plugs, cleaned wire connections.
Next is timing/balance belt/tensioners, water pump, accessory belts, quick-struts all around, frt & rear lower outer bushings @ the strut & frt & rear endlinks.
Just loooking to maintain it.
