I just got a h23a1 prelude SR 4ws, I love it but I've found that theres a bit of white smoke coming out of the exhuast. The muffler itself has a 3" tip. The smoke is white coming out about 2" from the tip of the exhuast. When I floored it, my friend said it did not grow larger.

I think theres a coolant leak, but where? Headgasket? waterpump?

Thanks

Btw, I searched for smoke but gave me no results.

Seems like you have a slight seapage of coolant into the cylinder from your head gasket, white smoke is usually an indicator that water is being mixed with the exhaust gases. And as you have a slight coolant loss that would explain where it's going, so yes I think your head gasket is on the way out, you can also do a compression test to confirm this.

Could it be that the head gasket is loose? Maybe some bolts are not tighten?

Thanks

lude of pre 2.3

could be loose bolts but i doubt it yeah u pry have a hg problem but a compression test might not be right i would do a leak down test

Lil. Cease

i got the same prob. but mine pours out tons of smoke.

yup me too. i think mine is oil thow

Yeah sorry I did mean a leak down test, but even in the unlikely event that some of the bolts are loose, it would still mean that the head has to come off and be checked for warping and would possibly need skimming. Then a new gasket would have to be used and the head torqued down using new bolts.

Long long ago I had the same experience -> cracked head -> swapped to H22

i have same problem, but ive only noticed it when ive been low on oil. i have had a cooling problem a lil while back, but like i said i only really notice it when im low on oil. another reason i need to get someone to put my damn h22 in

my 5g is spitting out a lot of smoke lately. It started after i got test pipe, so I figure it was that

When the headgasket is leaking there is a loss of power right?

ANy good gaskets out there? or stick with OEM?

I'm going to try "gunk block seal" wish me luck!

lude of pre 2.3

stick with oem honda hg stock honda hg's are some of the best you can run even with a high HP application because they are a 4 layer metal design

Lil. Cease

so this is a simple repair? if so, what's needed?

I'm going to do the head gasket change myself this summer.

You'll need a manual for sure because you need to take out the head and cam etc. I 'm going to do my timing belt and waterpump while I'm at it.
