God I love Pull-A-Part Junkyards.. Got the Head (ok shape evidence of a burned exaust valve.. surprise #3 cylinder) got the intake, throttle body, IAC valve, injectors, fuel rail... pretty much the entire upper half of the engine for.... $82.56 usd :lol: Now to see if we can make 1 good head outta 2...

Custom - We did do the leak down test with identical results in my case anyway.. we can also hear the valves in #3 popping while the engine is spinning with no resistance. Possible one valve is sticking open and another valve is hitting it.. I found a 95 RS is a local bone yard.. head looks like it ...

the idle problems is because the cylinder will not fire at low RPM because of the low comprestion but when running around 2000rpm it does!! umm you likey have a burned Valve!!] Yeah thats the conclusion I came to as well.. thing is.. I need to figure out what caused this condition in the first plac...

Well I did a compression test on my 1.6L today.. and I did not find good news.. hope you had better luck with yours LOL I found 183/181/40/180 across my cylinders.. This definately explains my rough idle.. not sure what caused it though.. my distributor is definately worn.. its having troubles firin...

I agree.. all you have to do is unplug the distributor and take out the spark plugs.. then just go down the line one cylinder at a time. Have a buddy crank it for you while you watch the gauge.. even readings that arent super high are ok as long as the readings are relatively close across all cylind...

Thanks for the reply. :) Just wondering since there seems to be shared auto transmissions with some ford cars (probes & festiva's apparently) Just wondered if the also used this mazda engine as well. Lets face it.. A junk yard is going to put a higher $$$ on a mazda distributor than on a ford di...

Sorry man.. I dont know that much to tell you for certain.. I do know that compression ratio for the 1.6L DOHC is 9.40:1 So if you know what your compression ratio is supposed to be and its the same as the DOHC.. I would think then the specifications would be the same.

$30 isnt bad.. heck if you lived near me I would do it for free for you.. got the gauge.. there is a section in the online manual that I found that tells you the procedure and what min/max results to expect.

Basically I am headed for the junkyards to dig up a distributor.. but I have heard that the engine in my 94 RS is one that has been used in various different vehicles.. anyone know what vehicles besides the MX-3 that could have the same engine and possibly the same distributor shaft? Any help is gre...

94 MX-3 RS 1.6 DOHC - 120,000 - Needed Tires & apparently a disty... but going strong

Have you checked with a mechanical water temp gauge? Sometimes the electronic sensors & gauges can give false readings.. also.. if you or a previous owner ever used any kind of Stop Leak in the cooling system.. this stuff will hose sensors bad. Another thing that could cause this might be a air ...

Wondering if any of you folks have a spare distributor in good condition that you would sell cheap? Need one for my 94 MX-3 1.6L DOHC with auto trans. I live in the seattle washington area and have cash. PM me if you have one your willing to sell. Needs to be in good shape.. no worn bushings or exce...

Hey guys... as you know.. I am trying to track down a rough idle issue on my 1.6L DOHC MX-3. Well I may have made a little discovery here this evening and since it wasnt something I have seen posted here I thought I would share the wealth for something else to check. I was taking a closer look at my...

I am hoping to avoid the head job :wink: But if neccessary I am one of those lucky chaps that has a uncle who has been the foreman of his machine shop for the past 35 years.. so if neccessary.. I can get that done.. :) Thanks for the reply though. I think it might be a plug wire issue.. still invest...

Hey guys.. just bought a 94 MX-3 last week.. DOHC 1.6L with AT and only 120k miles on it. Seems like a decent ride and I am glad to see that there are a lot of people that are into these cars. I do have a couple of questions.. and yes I spent the past 4 days reading through your posts trying to find...
