So I was under the impression that the headbolts on my f22a4 engine in my 90 accord ex were NOT reusable? Anyone know for sure?

 

I know for sure that the head-bolts in 1998 were reusable. The factory shop manual has a diagram for inspecting them. Basically, you measure the bolt's diameter where the procedure says (with a micrometer). If the diameter has necked down below the published spec, it needs to be replaced. All the bolts were OK when I did the headgasket on the 1998 we used to own.

I suspect it's the same for earlier years too. In the DIY forum area there's a post about download manuals.

 

Ive looked everywhere online. I have a pdf on the cylinder head for my car, does not state to inspect/replace/reuse. nadda... Kinda stuck here, Ive got a week til my parts come so I think I may tear down the motor tomorrow.

I personally replaced mine, if money isnt tight I would recommend it. If I recall it was about $80 for new ones.

 

I can't find a manual for the 1990? Is it crossover another year or years?

 

Yea I ordered them online, All the parts suppliers I spoke with about 4 of them said that I needed to replace them that the listing they have show a t2y for it.

 

Oh, I thought you didn't find the post altogether. 1990 should be the same as 1991 or 1992. I don't have an Accord from those years so didn't remember which year has a manual in there.

 

reuse the bolts you will not have a problem,i have reused bolts on all the head jobs i have done (dozen upon dozen ) nevewr had a problem,, make sure you torque properly

 

Ive always replaced head bolts. Seen a few fail. Prob because they didnt no what they were doing but i still replace them.
