    Leaky cowl causing misfire?

    ok, perfect timing!! Just this evening I was checking my socket against plug and thought exactly that - then checked back at the thread and exact same thought! I think they’re available with a rubber grip or magnetic maybe - will test with a 5/8 plug in store. One additional cowl leak area I...

    Leaky cowl causing misfire?

    OK, thank you! Some more novice questions if I can ask for advice please. A mechanic replaced the plug and coil on cylinder 4. I was quite keen to try doing cylinder 8 myself as I already have the parts. Can the plug be installed without needing to remove the fuel injector rail and is that...

    Leaky cowl causing misfire?

    @mountaineer2004 Thanks for those shots and replys to questions. Super helpful! With the engine cover, it lips down at the back but the lower edge sits pretty much directly over the top of the 4 and 8 coils. Then combining that with the fact that the cowl holes are located that when leaking...

    Leaky cowl causing misfire?

    Hi All, First up, so appreciative of this forum and the wealth of experience behind it! Thank you! I have an issue with rough idle that I’m almost certain is as a result of my cowl leaking water into the 4 and 8 coil & plug wells of my 2002 Explorer v8 Limited. At first I thought maybe the...

    Fuel Cleaner Recommendations

    Ok, thanks all. Seems like Techron and Marvel are the way to go, I’ll get some shipped. A question on fuel cleaner. Is it even necessary? As mentioned my Explorer has been unused for an extended period and some engine work recently done but its since had the old gas run through to empty and an...

    Fuel Cleaner Recommendations

    Thanks all for your help so far! I had a laugh at the Marvel Mystery Oil till I checked and see it's an actual product!! I'm in New Zealand and having trouble finding all of these here and trying to avoid shipping as we pay $1.65 to every $1 USD in exchange presently. So once I add shipping...

    Help identifying a part for engine repair - Blown Spark Plug

    Just to follow up on this thread. The thread was indeed confirmed as being stripped by an independent mechanic’s endo inspection which I could also see on one part of the thread in my endo shots - even though it was out of focus. It was cylinder 3 that the plug blew on the head (V8)...

    Fuel Cleaner Recommendations

    Hi All I have a 2002 Ford Explorer 4.6L V8 Limited Edition (UT Model) that is idling roughly. Before I address the plugs and coils, as a first step I will try a fuel cleaner - maybe the injectors? Can you make make your recommendations for what brand/cleaner you have used with success please...

    UT, UX or UZ Model

    Thanks for helping. I found this link which outlines the Aus models clearly... http://australiancar.reviews/reviews.php#!content=review&make=Ford&model=Explorer&gen=224 Mine is a UT and Ford NZ confirmed this. As far as I can tell the plugs are the same, the only difference is the gapping...

    UT, UX or UZ Model

    Hello Community A novice question. I have a 2002 Australian Ford Explorer V8 Limited. Am I correct that it is a UT Model. I've been looking at parts, specifically spark plugs and can see there are different plugs for UT as apposed to UX and UZ. I'm assuming that possibly some changes were made...

    Help identifying a part for engine repair - Blown Spark Plug

    I remembered I have a 45 degree mirror that came with the endoscope so was able to take shots of the heads pulg thread area. The only challenge being that the endo is optimized to be about 4cm (1.5 inch) away from what it's looking at otherwise it loses focus. So my lesson being to own and endo...

    Help identifying a part for engine repair - Blown Spark Plug

    Yes agree whole heartedly. Over to the mechanic now. My initial goal was to understand exactly what happened (of which everybody has been very helpful thanks!) and repair myself if possible. But at this stage it seems wisest to lean on the expertise of the mechanic for the way forward. A very...

    Help identifying a part for engine repair - Blown Spark Plug

    Edit: I found a video of sombody performing the CalVan 38900 installation that includes an endo inspection of the plug well area BEFORE the installation, as below. from this video here; It seems the blowouts can occur because there’s only a few threads for the plug to cling onto in the...

    Help identifying a part for engine repair - Blown Spark Plug

    Just thinking perhaps the only way I can know if the current plug is still partially in there or not is by removing one of the other coil and plugs, then do a comparative endo shot. Unless somebody else has a shot into a cavity with no plug in? I'm trying to assess what I may be able to do...

    Help identifying a part for engine repair - Blown Spark Plug

    I ended up discussing it with a local mechanic who said just turn it over to blow the water out. They're well versed on many different Fords so decided to take the risk. The water blew straight out so I only ran it for less than a minute. It turned over immediately and seems to run fine overall...

    Help identifying a part for engine repair - Blown Spark Plug

    ok, bone dry and good shots. New working theory - is part of the plug still in there, just the top white insulator has blown off? A local mechanic suggested this without having seen shots yet. The piston looks pretty clean??

    Help identifying a part for engine repair - Blown Spark Plug

    I got an endo camera and took a few shots. It's not the greatest res but gives the general idea. The shots are moving down the cylinder, reading left to right (first being out of cylinder, last being at the hole at bottom of cylinder). As soon as I pass the camera through the hole everything...

    Help identifying a part for engine repair - Blown Spark Plug

    Thanks for everybody’s help so far, much appreciated! I have an inspection camera on order which hopefully connects to my phone and should arrive early next week. Once that turns up I plan to dry the well with a sponge, air blast to help move off residual water (aerosol can) and get shots in...

    Help identifying a part for engine repair - Blown Spark Plug

    ok, thank you. I found the CalVan instruction video. Also, this CalVan end user description of what the vehicle sounded like when the plug blew out on his Ford (at 35 second mark)… ..."like an aeroplane engine all the way home - took the coil off with it" sounds identical to my...

    Help identifying a part for engine repair - Blown Spark Plug

    ok, that sounds hopeful! The Explorer has been regularly maintained, serviced about every 10,000kms since I owned it at 60,000kms (130,000 now). The plugs have been replaced (long life) at about 100,000kms. There has been slight engine missing under load in recent years so maybe this is why...

    Help identifying a part for engine repair - Blown Spark Plug

    These are the best shots I could get with top off. 2nd in on left side of engine. I'm not sure what I'm looking at in the cylinder. There's limited space I can get my phone in there so got as close as I could above cylinder. I could try and source and inspection camera to get in the hole? Thoughts?

    Thanks! haha, yes I can imagine that’d be like sending a bolt of lightning through the body! Yes if you can help with suggestions for the parts would be appreciated! Do you think it’s Ok to replace just one or all 8 at same time? I will sell it after the repair is done - I don’t have space for...

    Help identifying a part for engine repair - Blown Spark Plug

    Hi All During this last year while travelling home in my 2002 Explorer, I had an experience where an engine part failed that literally resulted in the engine sounding immediately like the exhaust had detached so that there was no baffling to the exhaust sound. The running engine became very...

    Low Oil Pressure

    Thanks very much for that. Yes I though that might be the case but it's really helpful to hear it from other users experience as well to confirm everything is ok. It has probably always been the case that it has come on as described, however I have never noticed it until the mechanic pointed it...
