Ever since doing the timing belt project, valve-stem seals followed by removal/cleaning of intake manifold, I've been working through various issues that for the most part have now been solved. I've started a new thread to cut to the chase of the one most troublesome problem remaining: I'm...

@pcb do you have a link to your thread? I'm going to borrow a fuel pressure tester in the next few days, and if I can figure out how to use it I'm going to test that. Still doesn't explain the ridiculous oil loss/consumption though. Also going to re-check the engine compression. Anybody...

Hi pcb, Thank you for the input and that particular troubleshooting page - I have the full service information just hadn't gotten around to checking that section yet. I'm hoping someone with similar issues or whose heard of similar will chime in. Seems odd for the fuel filter to suddenly...

Just don't leave any roof open when it's raining... ;) UPDATE: I finally did the suggested test - phase 1. I have oil in in my cylinders with a cold engine. The first time I did the valve seals (new from Mazda), it was my very first time and I used a 1/4" drive deep socket (9mm I think?) to...

Interesting. It seems like your engine purchase was not quite as described - what is the difference between FSZE vs FSDE? I would definitely not be happy about broken components! And what is involved with the MP3 flash? I used to have a Ford F-350 (gas) with a Livewire programmer and custom...

Huh! Now you have my curiosity peaked MrGiggles! Do you have a link to the build thread you speak of? I looked in your profile and don't see any reference/link.... sorry... new here! Is your vehicle manual or automatic? Where do you get these engines, how do you find a reputable source in...

LOL thanks for that pcb - I will give that a try. I can state in advance that if the test reveals leaky valve stem seals after installing two completely new sets of seals (from Mazda @$160/ea) within three weeks of each other (didn't want to have to take the top end apart a third time!) I will...

The car has very little rust - just a few little spots here and there where the paint got chipped from road debris. This car has the original transaxle and engine and seems to have been well looked after. Certainly I have taken very good care of it and performed several upgrades. I doubt the...

What do you mean by lower end being "okay" (or not okay)? And what is a JDM engine? And where do you even get rings/supplies for this sort of project? Just curious...

Hi Maroon, The camshaft seals are fine (from Mazda) - it's the new crankshaft seal I installed (two separate installs). The original seal wasn't leaking, however since I was doing the timing belt I elected to replace (mistake!!!) it since the car/seal is 12 years old. Despite my care during...

UPDATE! Thanks MrGiggles for your suggestion re impact screwdriver - found a smaller version at Princess Auto and pre-soaked the screws a couple of times uusing Tri-Flow LPS2. Came apart with little effort and no damage. Cleaned everything up and put new IAC gasket, new throttle body gasket...

Actually the bulletin is for the VICS AND VTCS screws. http://www.protegefaq.net/tsb/3005C.pdf I had my intake manifold apart last week for cleaning, and discovered I was a "victim" of this problem - only because I discovered my #3 and #4 VCTS butterflies were each missing a screw, and the...

Huh! LOL I tried a poor person's version of that this afternoon (whacking my screw driver with a hammer - to no avail). Princess Auto apparently has a similar item - I'll try that out tomorrow after I pick up the IAC and throttle body gaskets. Happy to find the correct size e-ring for my VTCS...

Thanks for that. Yes the battery was unplugged yesterday while I was messing around... out of curiosity how long must the battery be unplugged to reset the PCM? Since I posted this I've been digging around online and have found that the FS engines quite commonly had the IAC gasket leak...

UPDATE>>> Some issues resolved, but I think I definitely have a coolant leak (not head gasket) - IAC gasket??? Ok. Yesterday I resolved to get to the bottom of things before driving the car any further - particularly in the case of a coolant leak running through the engine. I disconnected...

Thanks! Yes, strange indeed. So while I had the IM off the car I forensically cleaned the fuel injector port in the IM. Soaked the new Mazda seals in synthetic oil and installed in the head, replaced the fuel rail as you described in your thread. I didn't mess with the upper o-rings because...

I'd like to say I'm offended by the suggestion (coolant hose to vacuum line) however something is clearly amiss and mine are the only hands that have been inside the engine. I'll check. Actually if I don't see anything obvious my intention was to replace the new EGR with the old one before I...

Yes, but how to explain this smoke (and it's a hot summer here) ???: <iframe frameborder="0" width="560" height="315" src="//www.dailymotion.com/embed/video/x337sxa?autoPlay=1" allowfullscreen></iframe><br /><a href="http://www.dailymotion.com/video/x337sxa_20150826-190818_auto"...

(FINALLY SOLVED!!!) Massive smoking issue & other problems... 2003 Mazda Protege5 The ending of the saga... is happy - and can be found on page 7/8.... loving my P5 once again! (updated October 19, 2015 - tried to change the title of the main thread but I guess you can't)...

Really? Nobody runs diagnostics on their vehicles? Any insight appreciated - hoping someone will help a Mazda newbie out! Thanks!
