Top hat gets hot

Yesterday, 09:53 AM

Fresh rebuilt motor and full rebuilt TBI with new FPRnon adjustable for now. Car runs and boosts great with no issues at all, but noticed the top hat gets as hot if not hotter than the valve cover. Shouldnít it be cooler since itís got fuel constantly passing through it?

WTB a few items

Looking for a stock air can lid from earlier models without the extra enrichment tube/valve. Also, need a manual transmission bell housing cover to fit an 88, and the large washer that goes over the AC idler pulley. Tia

Found roller rockers on intake side only

23 July 2018 - 05:42 PM

Doing a rebuild and found my old valve train has roller rockers on the intake side only, that I was going to just swap over to the new NJV M28 head with oversized ss valves. Any concerns from the old proís here doing this? It ran like a champ for years before the head gasket gave out, so Iím leaning towards reusing as-is.

Secondary air issues

19 May 2018 - 02:13 PM

Anyone familiar with how this is supposed to work/cycle? Mine seems to work/run when car is cold started, but when car is warm it seems to cycle off for an instant, then back on, repeating indefinitely at about 3-5 second intervals. I canít just ďrip it outĒ, since Iím in CA needing to pass smog test to register it. 25 year old rule doesnít apply here anymore. Even if I faked the visual stuff, the idle raises and lowers along with the cycling even if I disconnect the secondary air solenoid plug.

ECU O2 code comes and goes after warm

13 April 2018 - 05:16 PM

I have an led hooked up to the diagnostic full time to see while driving. Brand new 02 sensor is installed. Car will flash 02 code for a while, then back solid on, then back to 02 code, back and forth. This happened several times on my 7 mile drive home today with ambient temps in the 70ís (so cal). I immediately tested the CTS after getting home, and it ohms out good at about 200. Even when the light was on solid, the car was choppy on idle thru moderate throttle. WOT was all good. Itís been a while since I did a TPS/ISC reset, so Iíll get to that and throw the Mazda TPS upgrade I have sitting here. I would like a clue what else could be a factor here before doing the reset, so I donít complicate problems setting it up
