Well i did a mini me a few months ago (d16z6 head on a d15b7) and last week i noticed a pretty nasty valve tap (or sounded like one) and I took the head off and I noticed marks i guess you could say from the valves.............Now what im wondering is..........are those pistons ok? i plan on getting the head rebuilt


Thats the head that came off

 

id sand the valve grooves down but youd still be able to run them.

 

that doesnt look too good...

 

Thats odd because the valves dont look like they touched. If they did some of that sult would come right off. You could always clay the motor and see whats going on.

 

someone didnt set the timing right. but it will b alright to run but make sure the valves arent bent

 

yeah the timing was not set right and i was stupid and decided to drive it around.............as for the head im gonna get that rebuilt

 

does any one else find it odd that the valves hit outside the valve reliefs?

i do...thats weird

 

so do you guys think there alright?

 

whatever you do, buy a HG for 96ex, that way its metal, not a composite junk one like 92-5's have

 

the 92-95 head gaskets come metal too. i remember getting it for a customer from the dealer. i know it depends where you buy it. same goes for the exhaust manifold. none of that felpro crap

 

Definately get the head rebuilt and check to see if any of those valves are bent. I bet they are.

As for the pistons, I'm sure you could smooth them out and use them, but you can pick up used pistons/rods that are in perfect shape for like $20. I would just do that instead if I were you.

 

were can you get pistons/ rods for $20?

 

I can't believe you didn't wreck anything else. I would recommend replaceing some pistons. and maybe valves.

No. They are PM3 non-VTEC pistons with smaller and closer valve reliefs and he is using a VTEC head.

 

oh ok makes some sense now, didnt see that part before

 

No those pistons and valves are fucked. Way to go

Just saw em too. 12.50 + Shipping

 

maybe i should just swap a b16 in there

 

what problems you think i would run into if i were to rebuild the head and throw it back on with those pistons?

 

anyone?

Just save yourself the headache later on down the road and just get new ones or used ones that are in better shape, i mean you already have the motor open.

 

if you put the timing on correctly this time it will be fine. ran into this on a customers car . car can in not running and he said he just replaced the timing belt himself. i think he is still driving on the same motor as far as i know.
