My '88 Stock Engine issues (Page 1/2)
Fiero Vice FEB 05, 02:13 PM
Hello,

I have '88 GT 5 speed with 53K miles.

I have many things that I would like to solve with my stock engine, but need your feedback on priorities.

I suspected I might have leaky valve seals when the car starts up with a lot of smoke.

I would like to take care of that along with water pump, replace headers, intake & manifold gaskets, vacuum lines, Rodney's Ultimate Getrag Shift Kit, replace some sensors, and maybe exhaust system.

I'm debating if I should take the engine out or not.

I will consider switching over to 3.4 pushrod, only if my stock engine goes bad, but afraid it will hurt the value of my car.

Since my engine has low miles, I think I should stay with my stock engine and update & upgrade whatever is needed.

What about crankshaft? Should I upgrade it to 3.1 crankshaft?

Should I go for rebuild while I'm at it? At this point, I don't think it's needed.

So, I'm a bit confused about where to go at this point. I don't want to have to take out engine again & again if something else pop up.

I'd appreciate your opinions. Thanks.

What color is the smoke on startup? Does it smell sweet?
Fiero Vice FEB 05, 03:31 PM

White smoke & lots of it. No, it doesn't smell sweet at all. Just pollution & maybe fuel.

If it was me I would keep the low-mile stock engine and just work down a list of repairs.

White smoke is water/condensation.
Blue smoke is oil.
Black smoke is (excess) fuel.

I will agree with above. Its probably condensation. Id just working down the list of repairs.

Thanks for your opinions.

So, it can be done replacing headers inside the engine bay?

White "smoke" just after starting and a bit after maybe condensation. That will quickly stop.

White "smoke" w/ engine at operating is likely Coolant problems.
Intake and/or caskets to crack head etc can make engine to "burn" coolant.
Head issues can "fake" boil over too because cyl have way higher pressure.
Intake has coolant in them and caskets can fail. If morons replace coolant senders/sensors then may have crack the intake when they over torque the part.

⚠️ Warning: Do Not breath white "smoke" or coolant steam anytime!
Ethelyn Glycol can kill you and "smelling Sweet" may not be there to warn you as other fumes can mask that.

Fiero has SS exhaust and replacing it won't help you. Low mile engine is unlikely to have Cat problems unless has "burning" coolant problems.

if let parked for mounts to years, Water Pump can go iffy/bad just for that.
Coolant goes "bad" even w/o engine running and won't protect for "rust."
Even w/o that, parked WP can get rust on shaft and eat the seal when running after. WP Seal isn't 100% "water proof" and tiny bit of "leaking" coolant lubes and anti rust the shaft.
(Other seals to same for axles, crack, and brakes.)
If replacing WP then Flush coolant too.

Thank you, Theogre, for your advice.

I'll give you my 2¢ and it probably isn't worth half that. Do what you want to your car. These things are collector cars only in the minds of the owners. There is no value to retain. Consider any money spent as just that: spent. These cars are not investments. While the '88s may be the best of the bunch, they're also a pain to get some parts for. One example are rear calipers. They're made of unobtanium. Pontiac may have made 400,000 or so Fieros, they only made around 30,000 '88s. '84-'87 have a better parts availability. If you'll be doing a lot of engine work, here's a few reasons to pull the engine. Great access to everything. Murphy's Law says you'll break or strip a bolt or two. Do a motor refresh. Do everything that needs to be done plus preventive maintenance; like maybe the timing chain, etc. Take advantage of the engine being on a stand and hopefully you'll be rewarded with just having to do oil changes for years to come.

Oh, if you want something fast and older, get a first gen F-body. They're faster. There are brand new parts galore and will be for generations. They are super simple to work on. My Fiero's big brother is the '68 Firebird sitting next to it.
