[s-cars] Borescope'ing the oil pick-up

Thu Sep 16 12:19:00 PDT 2010

 You gotta do what you gotta do.... but if it were me, I wouldn't run that car another second if you suspect a slight rod knock.  There is an outside chance that a bearing is starting to go, and that the crank surface is still good, and the big end of the rod is not out of round.

If the stars align and the above is true, you could change your rod bearings, re-check you clearances, and be down the road for $150 and some elbow grease.

If you run it further, you may be pulling your engine for a rebuild.

I agree. What I figured is that things would look good in there with the scope, meaning clean. Soo, I would then know I had to schedule down time in my garage to get it sorted.

Visiting someone I talk with when I get the chance, while I drain my oil (even into a clean jug, so i can pour it back in) and dig on his fancy tools, sounded better to me than dropping the pan and having a tied up garage for a week, being I could delay for a week and beter schedule the time.

OK....

Now I really don't care about your control arm bushings, or any other front end hardware.  You need to pull your pan, and you need to measure your con rod clearances.  If it is in fact rod noise, you may still have a chance of being able to sort this out with the engine still in the car.

//Siiiigh,

Theres a noticable, what sounds to me like a rod knock, slightly below and into 3k RPM..

It doesnt happen at all when cold cold and oil pressure is steady high. It doesnt happen under boost (at least not noticably, yet)(did I say yet..oops) or deceleration. Once warmed and light on the throttle it is quite apparent to me, but I did have to point it out to my friend.

kinda wanna puke, kinda staying optimistic, but im pretty confident Lucas and Amsoil are not the cure..

 No doubt your experience may have been different, but I got mine out just pulling the front bolts.

Back to the original issue... what makes you think your pickup might have issues?

Not saying remove the control arms, but break the bolts free & drop down along with the 2 front and 2 rear sub-frame bolts.

I thought the CA bolts went through the sub, into the body. I dont remember getting enough play out of just dropping the front like you suggest. Or maybe I was uncomfortable with the stress I was putting what remained attached.

Whatever the case, I do remember trying to be minimal about removing the oil pan and it turning into more than just two front sub bolts to get it out.

Seriously, you can get the oil pan out by just dropping the front of the subframe... no need to touch the control arm points.  BTDT...

I know, but I just replaced the control arms and im a hardware freak. "Always replace" may not mean always, as I remember you speaking to before, but my policy is to replace them every other time and they've all been re-torqued once..

 If you've got that sort of concern, I'd just drop the oil pan... it isn't that rough.

Brian,

17-3 of the AAN engine manual shows the pick up in illustration 17-303, looks to 

be in the front to me.
Here is a link where you can download the manual in pdf format.

Hi list,

I am concerned that I may have a contaminated engine oil pick-up screen.

Wondering if anyone has had any success using a borescope in the oil pan.

I forget, but ithought the AAN pick-up is in the front of the pan, but
forget if the baffles, however minimal, or dimensions make using a borescope
for this task even possible, going in through the drain plug hole.

A colleague of mine has a snap-on borescope with fancy lighting effects, but
if it cant even contort into place, whats the point.

Just typing to know if theres any BTDT for this scenario.

thanks, Brian
