I have done the research on thezcresource.com to find out the differences, however on my engine the marking are gone...I was wondering if anyone could thell me the visual differences between a SOHC and a DOHC ZC engine?

Thanx Kyle

 

The DOHC has a very wide valve cover, and two cam gears.

 

The DOHC will have a black plastic cover -on- the valve cover opposite to the distributer. Also.. DOHC will have a 'ribbed' style valve cover and the SOHC will have a smooth valve cover.

Have someone show the how to tell the difference from an engine with 2 cams compared to an engine with only 1.

 

DOHC ZC



SOHC ZC

 

I thought the 1 to 2 cam difference would be a dead giveaway .......

 

i wonder if my a6 is DOHC? hmmm

 

no, the D16A6 is a SOHC only, at least pretty sure it is. Its been awhile since i was into d series stuff...lol

 

The A6 was SOHC. I think he was joking. Or at least I hope he was.

 

mine looks just like this but is a dohc, I have seen both cams but have a valve cover that looks exactly like this? why is that

Ummm,, you might be mistaken on that one.

 

well it may not look exactly like that, I havent seen my car in a week so its fuzzy. But I know that it is not the valve cover with the dip and the plugs in the middle. My plugs are at the back of the cover. Its a jdm dohc if that matters? I know its a dohc because I took the cover off a few times

Is there a dohc with a valve cover with the plugs on the back?

If its a DOHC the spark plugs are in the center. I think you saw the rocker arms when you thought you were looking at the cams?

 

wow I really dont know. I bought it off ebay and it was listed as a dohc. BUT The valve cover my motor came with had a leak from a dent so my dad was able to use the valve cover form my blown engine. Would a dohc cover be interchangeable with the stock 89 Si motor.

Should I start to cry now?

 

umm, if you were able to put a valve cover off a sohc onto it, sorry to tell ya man, but your engines a sohc...
all of the dohc's had the plugs down the center of the motor as far as I know.

 

Not to thread jack, but where do you buy a SOHC ZC...?

 

wow, thats pretty funny...sorry buddy.

 

wow that really is fucked. Im honestly pissed now. I never really paid attention to it since it was just to replace my blown oem motor but **** the guy scammed me. I didnt really care and Ive never gotten a chance to drive the car yet quick since Im pretty much going show and audio. Think I might get looking into a 65 shot. ****

 

Does this pic mean two cams can be on one side?

and if so dude, you might not have got screwed!
