low oil pressure going to xado it
« on: February 04, 2015, 01:13:09 PM »
 Well my 78 2.3 always had 44 or so psi at idle and would go up to 60 or more with rpms raised. It was the same from 1988 until recently so its not been a gradual change.

 Now it starts out just under 40 at cold idle, and will climb some to 45-50 maybe with rpms raised and held steady

 Hot it drops to about 35 and wont get back to 40 with rpms  raised.

 I think this came about a few months bck when I drove a few miles with no oil pressure. The stupid little hose from the oil pressure gauge broke.

 So Im going to try that xado and see if it helps.

 In case anyone is interested I will post my results and observations in here.

 Anyone know if it would be best to change the oil before I begin the treatment? Doesnt have a lot of miles on the oil and filter but probably 4 or 5 months. Ther car was sitting with the bad starter and leaking vc gasket, while I drove my vette.

Hi Toni , glad you got your starter changed and got it running , on the oil pressure it might not be anything wrong , the line that broke was it the very very small white plastic line , if it is the cold may have something to do with it, one, if it is below freezing the oil may be to thick to sent the gauge the right pressure , and also will make the line very brittle and hard and will break very easy if it had a small kink in it , hope you did not lose much oil when it did , they pump a lot of oil out on the road before you know it, if it is losing the oil pressure it is not much, you may have a sticking oil pressure relief valve, if your going to use a treatment use the oil you have in the engine , after a few days the pressure does come back up the valve was sticking , it happens more often in cold weather because the pump housing is aluminum and the valve is steel,

 When that hose broke 3 or 4 months  ago, I los two or three quarts of oil. I actually think I lost most of it when I left home and didnt see the oil gauge until on my way home, at zero. Found the puddle and trail when I got home. I drove it two or three miles to get home anyway at zero. I thought it was probably done for anyway. Maybe the slick 50 I put in in 89 or 90 helped.

 Anyway I got the xado today going to try it I can hear some rattle in the motor too someone told me it was loose rods, more tinny sound than a lifter I think.

 And yes it ha  the small white plastic tube I put a new one on it last year after it happened. I think I noticed less oil presure after  replacing the 3 quarts it lost :( I was just happy it still ran as well as it did then. Now I want to see if this helps it.

that is bad,I had that happen to me years ago , and the one reason I will never use that type of line again, I use electric gauges that have senders and no lines to break , did not know that you my have run the engine out of oil, may explain the lose in oil pressure you have , the treatment may not help, the treatment is a cleaner and will make the oil thinner and you may see a lose of a few more pounds of pressure on the gauge , if you do the bearings are gone, if the noise is not getting worse you may be lucky and not have damaged the crank,  one is pull the pan and have a look at one of the rod bearings , a big job for someone that has never done it before , you can change the main and rod bearings with the engine still in the car , if the noise gets worse, do not drive the car anymore until it can be fixed,

 The noise doesnt seem to be getting any worse I may be seeing a psi or two less lately. Xado is a ceramic treatment thats supposed to coat parts and a lot of people say it raised their oil pressure again but we`ll find out

here is a photo of the bottom end to give you an idea , and a rod bearing , the pinto crank is very tough ,I have seen  bearings down to the steel backing and the crank polished out and did not need to be cut undersize ,

I personally would not waste five seconds with that product but do as you will. Just like in the fishing industry and why they keep designing new and more colorful lures to hook them again and again. The eternal grasping at straws.

The oil pressure drops because the soft bearing parts are dead and they aren't made of steel. Much better off doing as pinto_one suggests.

Absolutely no one will EVER convince me you can simply rebuild bearing race steel like that. The website description of how they do it wouldn't hold up under true scientific analysis. 'Uncompensated bonds',  that's a good one........... ........

I have to agree. Metallurgic snake oil.

 I had a little red lazy ike lure once that really worked great those silver ones that look like a fish didnt do a thing :)

 Since we got surprised with snow it will be this weekend when I give it a shot. Just posting for anyone who wants to follow I wont be more surprised if it helps than I will be if it doesnt. But theres a lot of people who say it has done things.

Besides it not working, my concern would be, say it does stay on the metal, I don't see it lasting in any friction area, particularly in scorched areas. But I can see it clinging to the inside of the oil journal passages. I'd say it's a recipe for pinto stroke!

Look at their 'science' there as partially expounded by them and think it out........... .........if the 'metal' only rebuilds at friction areas of the engine then every rub point in engine would fill up to lock the engine up. They themselves say the 'metal' fills up all clearances. NOT doing so means the filler 'metal' whatever that could be is NOT hard enough to resist wear. The catch 22 there and impossible.

And using an engraver to mark up bearing steel? GOOD bearing steel is virtually untouched by an engraver BTDT. Even diamond tip ones. AND absolutely no way is a coat-on type plating going to replicate the toughness of that 6 ways from sundown heat treat, no way on earth! They speak of 'factory machine marks', all bearings micropolish to finish and virtually no rotational marking on them that can be perceived by eye at all. If so the bearing is junk before even used. So, they do not even know what they are looking at. I do, a cheap non-hardened piece of steel and not bearing quality at all. No rebuild process on earth can rebuild chipping in a super hard bearing surface. You start all over with brand new part.

As to what other people say........... ............I sold lots and lots of engine and trans additives while I was in the parts business and can say other than using intended lubes any gimmick claims of rebuilding were just that, NONE of that stuff works. I lied to customers just like all other counter guys are pushed to do. The human mind being what it is is what warps people to claim they think things are better but most were only fooling themselves.

Why I have never run any sort of special fuel or engine/trans additive other than proper clean oil or whatever in any car over 45+ years now. I can come up with a whole list of reasons NOT to use them as well, they often damage cars if they go past doing nothing.

 Well so far almost 300 miles almost ready to add the second tube of three. Another 600 miles I can say its helped or hasnt.

 One thing I know, when I took the oil filler cap off before while it was running a steady stream of smoke always made its way out. I assume with it off theres no way for the blow by to be pulled into the air cleaner cover.

 Now when I take it off theres no darn sight of smoke in there I looked and looked.

 At least no Pinto Stroke yet.
