So my oil exploded

[Rocketst]

Anyone ever been running a wot pull get a misfire off cylinder 3, an over retard on exhaust camshaft, over advance on intake camshaft then blow plumes of smoke out of the engine bay because your oil spontaneously blew out of the engine via the dipstick tube?

Mileage? Tune? Mods?

21000 miles, turbosmart 14 psi actuator pushing 29.34 psi boost, turbosmart BOV, 2jr intake and downpipe, whoosh v3 intercooler with charge pipes, symposer delete. Pretty sure my timing belt slipped. Tuned by Jason at dizzy.

Stock Turbo? Stock tune? I do believe that these engines are Interference engines but I'm not 100% about this...if it is and your belt slipped the motor might be done. Hopefully not....but the timing will have to be checked....does it run at all?

What gear were you in?

Won't start, by the time I pulled over the oil was drained. You could see on the hood where the fabric was right where it shot out from the oil dipstick tube. I was in 3rd year when I did the wot pull.

Typhoonfist yes everything else is stock. Sorry, if it's not listed I though you might assume. My bad.

The motor might be toast.....if you're really lucky it won't be. The 2j intake has been known to cause issues. If it was me I'd be re-installing all stock parts and see if it could be warranty able....or buying a boneyard 1.6. Good luck man! Maybe the oil filter failed? That's one thought....

Possibly but I just changed the oil yesterday... In fact I used penzoil 5w-20 and a k and n filter .. had any issues or heard anyone have any with these products

 

[Rocketst]

I did actually get the car to start though twice but heavy smoke and very rough idle made me turn it off

First step put oil in car, and do compression test.

Got it thanks. I'll let you know how it goes.

I had a similar incident occur, turns out I had cracked a Bosche oil filter upon installation (with my old tacoma). Oil was everywhere and I completely drained the pan while driving through the neighborhood. Fortunately, everything was fine, put a new filter on, and refilled it up with oil.

I hope its as simple as that. I find it interesting that it occurs the day after an oil change.

Lastmk7 that's actually the first thing I check, the filter and the bolt to make sure they were still on the car because of how much oil was under the hood. But unfortunately there was a very noticeable blotch of oil right above the dipstick and the dipstick being loose tells me it came from there. I just don't understand how 4 qts of oil could be put under so much pressure that literally all of it came out of that hole. It just screams blow by to me but I don't know how I'd get that much pressure in my oil pan or crankcase

Mazdaspeeds frequently blew the dip sticks under extreme crankcase pressures (lots of boost) without things upgraded PCV plates, vented oil catchcans, or at least an oil cap vent.

I don't see your mods, were you running more boost than usual?

Just saw your second post. Is 29psi known to be safe without additional mods?

Currently running 29.4 psi about so about 7 psi more than the system was originally designed for. I listed mods in first post as well as on my profile for the forums.

I just woke up and skimmed the thread. At this point what caused it seems secondary to the fact you may have damaged your valves among other things if your belt did slip. Rod bearings may be damaged depending on when and how much oil was lost.

Check for metal shavings when you change the oil.

Worst case scenario what parts are we looking at valves, timing belt set, what else. I'll just use them as an excuse to build I better and stronger honestly.

Who are reputable builders of these motors? They'll know what you need.
