This is my experience with MMP and all the stuff I went through because I decided to buy a “built” engine from them.
I purchased a built engine from Mauricio back in June when my first engine gave out due to a ringland failure. At the time I was going to drive to Texas to buy a used engine for $1900. I was contacted by Mauricio for a partial sponsorship on an built engine, I told him I didn’t want to spend a lot of money on a engine which is why I was going to get a used one. At this point he tells me due to my situation he could help me out and do the engine for $1900 and everything at his cost.
Well at $1900 and a partial sponsorship didn’t sound bad at all, so I took the offer. I was not able to provide my core because I couldn’t have the car sitting in the shop for a long time. So we both agreed and he was going to source a core him self and start the build on that engine. He did help me out with the core cost.
At this point I agree to everything he says and he sources out his own core. Well it turns out I still paid more money for other parts the core needed and had wrong with it.
I’m not even close to upset because I figured $1900 was cheap but this isn’t what I wanted in the first place. I wanted to buy a used engine and get it over with it. Anyways fast forward I pay a few extra stuff here and there for this engine and extra parts I needed to make this a solid build.
Fast forward a few weeks and I finally get my engine, I have 2 local and very trustworthy people install my engine. The install was a success and no issues at all during install. We ask Mauricio if we can check my old engine to see what’s wrong with it he agrees to open it AS LONG as we put everything back. Me not knowing what I’m doing decided I didn’t want to mess with anything on the old core engine, but they go ahead and inspect it and find out the pistons are bad along with cracked ringlands like we had figured.
Anyways my guys put everything back together and when the engine ships back to Mauricio it turns out some parts were missing ( I’m only including this part to make sure I tell ALL of the story ) we agreed there was a few issues and he got it taken care off and resolved the situation.
Fast forward again to around 1300-1600 miles on the new engine, I start hearing a small faint lifter tick. I start getting worried and message Mauricio about this noice. He asks how loud it is and ask a few questions and what not and we agreed an oil change and a oil anlisays was needed.
Upon this I take the car to a local mechanic just to do a quick oil change and put new oil to see if it quiets down the noice.
We find some metal shavings in the oil filter and that’s where I started to get more alarmed. I did the oil change and I left that mechanic to go to another shop to do an oil analysis. I had spaced out and didn’t take the old oil in. So the only oil they could take was the oil that had maybe 20-30 miles on it. So I sent that in for an oil analysis and it comes out perfect.
I however don’t like the noice it’s making and the shop says the noice is indeed internal.
I pay $1000+ to remove the engine and have it shipped to Mauricio - MMP I paid $298 for shipping. Upon the removal I found out I had a blown head gasket
Engine shipped to Mauricio - MMP and when they get to the engine they ADMIT it is there fault for not torquing the head properly.
Then this quickly turns into a pointing game where I get blamed for using the wrong coolant. Then from using the wrong coolant he changes the story and says I over heated the car. I tell him that’s impossible because I never had my car throw any codes at all. He tells me he doesn’t know how but I overheated the engine. At this point I talk to a very well known engine builder who Mauricio is leaking out all the info to about my engine and using his words to trick me.
I talked to that engine builder and he says it is my fault, until I tell him about my head gasket, that’s when he said oh wow Mauricio - MMP didn’t tell me that. That’s a huge deal. Because of the blown gasket there is obviously more damage caused by it.
Mauricio then wants me to pay and I tell him I’m not paying anything at all because they had told me it was there fault first and they want to blame me for overheating the car. I told him what in the world am I supposed to do when I get the new engine and it runs perfectly with no codes then it fails again because it “randomly overheated”. Because I honestly had no signs of any overheating issues. I’m not stupid enough to drive the car if the car is hot.
We don’t talk for a bit and tells me my new engine is almost done but that the new issue my engine had failed was due to too much boost. My logs which I showed him only make 24-25 psi. He then blames me and says that’s not always accurate. I tell him I use the logs and boost gauge to monitor my boost.
Fast forward to a few weeks ago and I receive the new engine. Engine gets installed and upon 10-20 miles I noticed a huge oil leak.
I take it to the shop to have it checked, in my head I think that this is an oil line that snapped off or something along those lines, upon inspect it turned out to be the oil pan gasket. I immediately asked Mauricio -MMP to see if he had installed the oil pan gasket new. Which he claims he did along with new bolts.
I had to pay $1100 for the labor of the oil pan gasket install. I’m an XI so labor isn’t cheap.
Mauricio - MMP did infact offer to send me a brand new oil pan gasket along with bolts. I had already purchased my own from my local BMW dealerships so I refused his offer. One of the main reasons I refused was because if this new oil pan leaks I knew he wouldn’t be held responsible, so now I’m down $136 of my money because I paid for the gasket to get this car moving since this is my 2nd engine from MMP.
I am not mad that my labor wasn’t covered the first time for the brand new 1400-1700 mile engine or something along those lines. I wasn’t even close to mad. Shit happens I gave him another chance.
I’m mad that my new engine with only 20 miles had an oil pan gasket leak and ALL I ASKED for was for him to pay half of the labor. I asked for $500 and him to pay the gasket and bolts. He refused and said HIS WARRANTY doesn’t cover it. I told him I don’t give a **** about his warranty anymore, if this engine fails I won’t be going back to the same person.
Apart from all this BS I’ve been dealing Mauricio keeps messaging a certain engine builder for advice because they have no clue what they are doing.
Overall summary is Mauricio is going to claim I got a engine at his cost. Which I have no clue if it’s true or not. After the $1900 and all the little stuff I had to pay the engine came out to about $2800-$3200 this doesn’t include shipping.
Now I’m more in the hole with this oil pan gasket leak.
To make matters worst this new engine with only 200 miles already has a good amount of blow by. I’m taking it to the shop for a leakdown test soon.
I know of 1 other person getting the runaround with Mauricio right now as well on his fully built engine.
I’m sure I’m missing a few little things here and there and I will defend my self at all cost with Mauricio when he replies.
My only option was to ship the engine back or ship the car $1400 or so for shipping. My warranty was voided upon my shop doing the work.
TL;TR
Mauricio -MMP first engine failed blamed him self then blamed me. Then new engine comes in and oil pan gasket leaks after 10-20 miles and refused to cover anything.
Happy thanksgiving
