metal shavings in oil - mccoy motor

[velox03]

well 13,000 miles ago i had a mccoy motor put in the ty. upon initial inspection there were some metal shavings. according to mccoy, this is ok at first. however, after many oil changes and 13k on the new motor i am still getting the same amount of metal shavings on my drain plug. it is quite a bit, enough to cover the entire plug compleatly. i had an oil analysis shop examine it and they said it was cast iron.

now i'm wondering and dreading... what is my next step. do i have to take apart my motor to find what is going on? this whole typhoon has become very expensive and time consuming... i really hope i don't have to go through another rebuild. i don't even drive it hard or anything. since i got the ty 4 years ago all i've been doing is trying to get it run right. any advice is appreciated...

much thanks, Mike

Hey Mike,

I would take it to that place in Tacoma and do the leakdown test. What do you see on datamaster, any knock? Have you given Jerry McCoy a call? I would be keeping him well informed on what is going on, but first get his advice on what you should do.

Cast iron sounds like it is coming from the cylinder walls or piston rings. Not knowing what rings they installed in the motor it is hard to tell. Is it using oil or making any strange noises and how is it running? I would be sure (as was stated) to keep McCoy informed as to what is going on at all times in case you have to do something to it later and there could be a warranty issue. I am assuming that you have a magnetic drain plug.

Before it was using more oil. but then i believe that was a result of a failed gasket. i had it replaced and now the oil level seems to be fine. i cannot tell if there is a funny noise right now. i am getting some knock from datamaster. about 2-4deg. at 10psi spike.

yes i am using a magnetic drain plug...

is this a sign of a failing motor?

thanks, Mike

You might want to contact Richard Le, I believe the same thing happened with his Mccoy motor. Dont remember what it ended up being, just know he is having someone build another motor now.

richardl@whitetyphoon.com

Richard are you around?

 

[velox03]

Thanks Spin for your suggestion.

yes, i have already talked to him about it. he told me he was just going to rebuild his old motor. however, i hope i will not have to do that because i don't have the time or money to rebuild the motor again after just 1 year.

what would be the best way to approach this? open up the motor and look to find what is going on?

thanks, Mike

I would say before you get too into this you contact Jerry McCoy. At least to cover your ass should anything odd happen. If you don't let the builder know of a problem then how are they supposed to attempt make it better.

 

[velox03]

does anyone know if he actually "warrenties" his work?

i have contacted jerry... he said he isn't sure. has anyone had problems with his motor besides richard and me??

much thanks everyone,
Mike

So Mike,how long you had this motor,like 2 years or so??
You have right? So how is somebody supposed to assume that you haven't beat the snot outta it (i.e. 30 psi,6500 rpm shifts,ect)for 13000 miles? I dunno.
You want a warranty???????? Throw in one of those fresh GM rebuilds and see how long it lasts.

My McCoy rebuild has got 20k on it with absolutely no probs,except for an oil leak that Jerry fixed FOC (Free of charge)

[velox03]

well thanks for the nice reply... always helps here...

i did not assume he warrantied his work.

and actually it's 1 year, 13k, and only 8psi. yes 8psi, i can't build boost after the new motor...

i'm just trying to figure out what to do... because i don't want to go through another rebuild.

 

[smeagol]

I can't believe you'd put 13k on the motor when you are still getting metal in the oil and you can't build boost. Some things are definitely wrong here, and you just don't keep driving the truck around while until you figure it out...

Do a leak down test, get the oil analyzed by a real lab (breakdown of what's in it). I'd wager you need to pull it and see what's up.

No shop will warranty any motor that is going to be put through boost & racing etc, but if you can pull it and show that it was due to poor assembly/machine work, Jerry may do something to help you out, make things right etc.

 

[velox03]

well at first jerry told me it was normal to get metal shavings at first. so for a while i listened to him. so that went on for like a while... (mind you this is my only car), and then finally i had a shop do an oil analysis. i had that done about a month ago. they said it was cast iron.

anyhow so i am in the middle now trying to figure out what to do, and i suppose i'll have to look in the motor.

 

[dlove]

If the motor has a 1 year 13,ooo mile warranty and you informed him of the problem within that year and before 13,000 miles then he should take care of it. Talk to him and straighten this part out and come to an agreement. If he agrees it was under warranty when you first brought it to his attention and he says to drive it that it is OK then drive it. By telling you to drive it he is accepting the responsibility if you do more damage. Make sure he knows that you are not comfortable with it and if something goes wrong in the near future that you expect him to make it right. Also understand if you drive it for an extended time (40,000, 50,000 miles) and it blows up that he really would not be responsible. He can't warranting it forever.

Hey Richard,

Remember me with the 92 Typhoon that I tried to do some tuning with Roland. Well we ended up blowing up the head gasket in that McCoy Performer Plus motor. It was only about 1500 miles or so.

Oh well, I had the engine pulled and machined. For extra isurance, we put in stronger head gasket with built in o-rings. I will be extra careful this time. The motor was assembled by my local mechanic shop.

I can't really blame McCoy or anything. But I was just disappointed

 

[velox03]

well richard i can't blame you...

when i had my motor installed it was installed in a shop in cali which only do high end cars... ferrari, ac cobra, etc... and they do typhoon's.

well, lets just say when the mccoy motor came in at first glance they were "un-impressed" the shop said at visual inspection there was WAY too much metal shavings which should have been blown out of there. also something so simple as a valve cover was put on crooked.

boostn, i also blew a head gasket. but that was not at fault for the build, but rather just a failed gasket.

i'm not putting anyone at blame. i am just trying to make my motor work... and i'm just stating facts.

thanks for all the help...
Mike

 

[velox03]

btw, i just want to make it clear that i am not putting down mccoy in any way.

he is bar far the easiest person i've worked with, and has great knowledge. just mind my situation and i'm just telling everyone what i'm going through so i can figure out "where in the process of my new motor did something go wrong." obviously something... the build, parts, install, etc... so, i am just trying to narrow it down.

i am also stating all this information so no one else has to go through this. maybe something went wrong on the build of my motor. at least then i can point it out to jerry so it doesn't happen again. or maybe it is a part defect, at least then i can inform him. he's a great guy and by far one of the friendliest and helpful ones in the business...

i just want to set things straight...

thanks, Mike

...hey, I appreciate your last post, it's fair & balanced. I am looking for a builder myself and it helps to hear info about people's experiences with different shops, but only if they are presented in a way that allows feelings to be seperated from facts. I wish you the best in getting this sorted out and your ride righteous & roadworthy.

Hey Richard,

Just try do what I had done. Have a good mechanic to take the engine out and have it machined and resurfaced. Perhaps, replace all the pistons with new ones. Have them put in O-ring head gasket. All that costed me under 4,000 dollars, maybe 4,500 dollars, thats including mostly labor.

If you want, I can refer you to the mechanic shop that I had it done at. I hope it will be better, and it should!
