Need some opinions or help

Ok so my DA9 head just got replaced with a new one , but it still has a misfire
my mechanic is trying to say its the block (Piston Rings)because he said it ran little compression in cylinder 3 and 4 !!! could this be true or scam

could be true if you had issues with the previous head it could mean you had more issues than just the head. If you are losing compression than there is more issues than just head it could be a number of different issues. If you trust your tech listen to what he says if not find another one and get a second opinion.

The last head jumped timing but i ran really rough and idle crazy but he said it was because bent valves and once i put the head on it the car will run better

Here alittle background it use to be the tech old car and he always asks me to sell it back to him and how he miss the car.

Before i took the car too him the car ran fine in higher RPMs like 3grand . it only missed at low RPMS like 1 or 2 grand. with no smoke or anything i actually drove it and it drove fine when the idle was pass 3 grand. but now he but a rebuilt head on it and apparently it misses the whole time in cylinder 3 & 4

it does sound like something is going on if it started running worse after he replaced it that is wierd. I recently had a timing belt break but luckily no valves were damaged. If the valves were bent then the they had to have hit a piston which could cause piston or ring issues. I would be careful with this guy if he really wants the car back you can't really know what he would do to get it, unless you know him personally. Just be careful and you might want to get another techs opinion and se if any fowl play has been done. Good luck.

yeah , the car did make a loud bang noise when it jumped timing , as for the tech i dont know him personally just know of his work he said the 3rd cylinder 45 and the 4th cylinder is 10

well it almost sounds like something happened within the piston chamber when the belt jumped and could have caused some issues with the pistons. Hard to say exactly what might be wrong without looking at it, the engine needs to be taken apart and looked at.

When timing is off, Or it jumps timing, or if the head is replaced without puttin everything at top dead center, you can bend valves or even worse, bend/break a rod. Sounds like you're having problems with your piston/rod, which could have happened when you jumped timing, but it's kind of rare.. Sounds like the tech messed something up when resetting the head on the block.

Thanks Everyone, I think im going to chalk this up as a lost and sell the car. I Really want a honda accord or GC8

sounds good but don't just sell the car cause you have issues with something that can be fixed, I have done that before and regret it. Make sure you really want to change into something else.

If i owned my dad's Accord i'd sell it to you real cheap. It's got a 4 cylinder, 230,432 miles, champagne colored, automatic, leather, sunroof. needs a new sensor in the bumper to get the SRS light to shut up (dad hit a dog a few years ago) and an oil change/tune up. Gets 28 MPG! (I hate the car) lol

I think the motor could be salvaged, i'd just get a second opinion.

@ Dennis just got the car back today, Apparently he did not let the car warm up to operating temp before performing the compression test. Also he said that the Idling has been clearing up more and more everday. The car still has 2 year old gas in it as well. I drove it about 3 miles and it ran fine the idle clear up and everything.

sounds awesome. good thing it was nothing serious. So you have a good running car again? It is always nice getting good info.

Yeah fuel knock is an interesting thing. Wish my old 4G64 had that instead of a knocking rod...

@dennis Yes the car is running fine just smokes at first start or first take off. Doing a valve cover gasket job hopefully wed !!!

awesome, hope you get it all taken care of. Always good to have another Honda on the road.

Yup. I gotta have SOMETHING to blow the doors off of. But i need to aim for bigger game than a Honda... I'm thinkin Evo? STI? lmao.

better be careful, some hondas out there will stomp on evos lol

Ah yes, the NSX. The baddest Honda out there. LOL. In all Seriousness admin, Congrats on getting your car running. Funny how things work out, you expect the worst, but get the best problem. Maybe i should change my outlook...

NSX is nice but I have seen civic's take on some pretty powerful cars and smoke them. My body was on his honda cbr 1000 and got left behind by an EK hatch on the highway.

Yeah, i heard about a Civic with a Corvette V8 in it in Northwest Arkansas. Never encountered it though, i was driving my brothers 94 'Vette at the time and wanted to race it.

I'm talking about 4 cylinder non turbo raw power civics. Things can produce good amounts of power with proper setup and tune.

And STILL get 30 mpg's! lol

oh yeah gotta love them japanese cars that can outperform american cars and keep running down the highway while everyone else stops for gas, lol.
