Well as what the topic states my oil cap has effed it today. And the fluck thing is just before i was about to go out i wanted to do a quick clean of engine bay and wash the car. What did i find the oil cap hangin off and half the thread inside the engine. "NOT HAPPY JAN" :eek: :eek: :eek: .

So i had to pull the rocker cover off, first time in my life i done such a thing. All went pretty smoothly and i found the chopped thread. A chip of the thread has gone, so as a preventative measure i bought $70 worth of fluids to be sure.
Firstly i put some oil flush in the engine then drain the oil and added new Mobil 1 and about 1/2 bottle of Nulon E-20.

So far the engine appears ok, and luck that the chopped thread was found. Only thing i'm abit worried is a chipped thread of the cap is somewhere in the engine, hope it didn't screw anything.

While the job was done to take the rocker cover off i detailed the engine bay as i went, so the leads are sparkling firewall green as and all the hoses blackened. Also cleaned the Throttle body abit.

Well so far all is well an the engine has been flushed out.

A word of advise for falcon owners if your car has done over 150k check your oil cap and replace it just incase.

heh.. dun worry about fux0ring your motor, I bought my Falcon and did an oil change on it first weekend, What did I find at the bottom of the icecream container? a little metal clip, looks like one you'd find from a carby kit.. Theyre very durable motors, but I can understand not wanting to get bits of plastic stuck inside it.

Does the piece of thread you pulled out match up to the bit missing from the oil cap? if so, then youre laughing!

Yeah the thread match's up, but theres a little chip of the thread that i couldn't find so thats why i done the engine oil flush and stuff to just incase eliminate the problem. Yeah i know what you mean engines are durable things. "Touch's Wood".

That happened to me on my ED not long ago. The thread practically crumbled into the filler hole. I got some long nose pliers and pulled it all out though, I know cos it matched up to a full oil cap, phew.
I got a new cap, its from an AU but has wrong info on it, says the wrong oil grade on it for my car. It fits well though. It says to fill with 10-30 oil or something.
I put much thicker oil 20-50 in mine. I once tried magnatec thats 25-40 or something, but My trained ear could hear a slight extra ticking noise on startup (just for a few seconds), so i pulled it straight out. But only after a few speed tests. It actually went faster. About 3 or 4 ks for the quarter mile faster. About 148 instead of 144 or so.
I may put it in again if i have a go at the drags

HEY Discokin6,

That clip you found sounds very similar to a retainer clip off a roll on timing chain - is it sort of oblong shaped, not just circular? If that's what it is, very nasty things could happen to your engine - you need to check your chain asap.

What happens with those rollon type chains is that people put the clip on the wrong way round and it gets flicked off when it contacts the chain guides (I know 'cause I've done it - incredible coincidence that I spotted it missing one day when I was doing a double check on the cam gear bolt after fitting a new cam - ie. coincidence that the chain connecting link had stopped at the top where I was able to see it).

Hahaha that makes me laugh, Thanks ED, But i just put in a new motor today.. lol!

hehe an 83 XE Fairmont motor, rebuilt by Veale, 2bbl 34/34 Weber, roller timing chain etc etc.. and IT FLIES! like 80 km/h in 1st, peaking at 5 grand, the rest of the story is still rosy as :)

Only problem is that the battery isnt charging :\ Ah well, i'm going to rebuild the other motor and put it into a dirt dragster or something like that, 400kg max with a Falcon motor, nothing will keep that back :)

But yeah, good to see someone on the ball there, but i'm pretty certain it was from a carby.. heh. That other motor was the factory motor, 600,000 km worth of tough driving in an XD wagon hehe

The strangest thing I've found in a motor was one of those smooth round pebbles like you find on pathways or rock gardens (about 12mm diameter). It was sitting sort of on top of the tensioner housing inside the front cover - heck knows how it got there!

One of the welch plugs went on me, and it overheated on me. When I realised what was happening it was too late, i was on a highway, so I didnt hear the valves pinging until it was already done, I could see black smoke in the rear vision mirror etc. Not Happy!

Oil Cap

The one on my NB Fairlane went at 90,000 km. Just screwed in on after an oild change and it crumbled into little pieces. Off with rocker cover and found it all but was less than impressed.
