Chevy & GMC Vans

I haven't seen it mentioned in awhile, so I had to do a search to remind myself that I wasn't dreaming. It was talked about over at the other site, but not here. I remember some people recommending the Napa Echlin brass caps or other brass caps as being superior to the aluminum AC/Delco cap. In September of '06 I installed the Napa cap. I went till June of '07 and was almost stranded on the Fl Turnpike. I did not think it could be the cap, as I had replaced it less than 9 months ago. Sure enough, I took it off and it looked bad. I bought a new one thinking it might have been a fluke. That one lasted till Oct of '07 when I went and got an AC/Delco cap. I should mention that I live in Florida and maybe the higher humidity contributed to the problem. The Delco cap that was on there before lasted like three or four years. Also, before anyone says anything the screen and hole were/are fine.








I just replaced my Delco cap and rotor after almost two years. They could have probably went longer as they looked to be in still decent shape, but they do have 40k miles on them. If I think about it, then i will take a pic tomorrow.

I have always heard AC Delco cap and rotor are a must on these vehicles. Every after market one will fail in a year. So far that seems to be the case from my own experience.

mine differs, I get longer life out of bosch caps with brass terminals.

Two year old Delco cap with 40k miles.

and?

As I said in my first post at the end, the Delco cap still looks pretty good. I could have gone longer on it, but I am trying to eliminate other problems. I don't know where you are in Texas, but maybe it is in a non-humid environment. In that case, you may have less trouble with brass. I just wanted to show with pics that brass isn't the best solution for everyone. You may say that is obvious, but when I was researching this there were a lot of people adamantly pushing brass awhile back. Honestly, the brass caps cost me more than the cost of three caps in a little over a year.

As I've mentioned several times before, you guys should take a look at Standard Motor Products "X" series caps and rotors. It's the only one I use and have used for more than thirty years. Never a failure. I have them on a '68 Chevy pickup that was last tuned up in 1993. They're still as good as new. When I did my Safari a couple of years ago I installed the same. I will never have to change them. Well, I will when I do the V8.

Good to know Smilie.
I can't seem to find a local parts store that carries them. Checked autozone, advance autoparts, napa, oreilly, pep boys, none of 'em have it. Looks like I'll have to order one from rockauto.com to keep on hand.

I just checked their website. They don't even provide a list of retailers.
