Engine Care & Tuning / Re: 1250 Motor Mount Issue
« Last post by RPM on October 30, 2023, 09:48:55 am »
Support the engine with a floor jack. Remove the bolts and the mount. Have a look down the hole to see if you can see any other cracks inside the bolt hole in the threaded area.

I have never come across an engine with both sides broken like that. There is no pressurized oil there, but there is a ton of oil sling from the rotating transmission.

Without slitting the cases, the only possible way I can see of trying to stop the oil is to try silicone. But that could be problematic if the case is cracked internally and the silicone hydraulics when installing the bolts.

You can remove the bottom half of the case without disassembling the complete engine. You would be able to get the crack(s) welded then and that will resolve the leak completely. If you do pull the bottom end off, you'll need a couple of gaskets and o-rings.

Let us know if we can be of any assistance.

Okay, understand a bit better know. I am going to guess that your case is cracked there. No good way to repair it.

Hey steve,
Thanks for the response. The oil is coming out of the vertical crack that the bolt is running into to hold the engine. Also that isn't JB weld it's the seam in the case where it splits open it seems to be the gasket you can see.

Hi Josh,
 Took me a bit to sort out your pic, but the video is much clearer. Not sure why you have that piece of pipe on there (the split one). It needs to be replaced with the proper mounting parts.
Your leak is likely coming from that long crack around the block that has been JB Welded. Block up you engine and pull that motor mount off. I am sure you will see where it's leaking.

This is the link to the video of the motor leaking. (File too large to upload on post).

Engine Care & Tuning / 1250 Motor Mount Issue
« Last post by Young Moses on October 26, 2023, 05:52:45 pm »
Hello,
I am fairly new to legend cars world and one of my cars had this issue on the driveshaft side of a 1250 engine the mounts are split and leaking oil when the engine is running (shown in video). My question is the following how could/should this be repaired? Furthermore how much would this cost?
Thank you,
Josh

For loose off, stiffen RF spring, raise tire pressure on RF, increase cross weight. I run with rear end square in the chassis. Find yourself a good tight/loose chart. https://www.rjracingproducts.com/uploads/2/9/4/1/2941827/legends_car.pdf

Setup and Handling / Axle skew/cross weight dirt discussion?..
« Last post by Doug10 on July 27, 2023, 05:50:12 pm »
Say it you have a car that enters great, good middle, loose on power off?. Axle is skew to the right for rotation coming off, running 47% cross. Would you add a few percent of cross to help with the loose off or would you square axle back up some? Both should accomplish the goal? allready soft on right rear spring, don?t wanna change that. Car is drivable and is fast but just wanna get my driver a little more confidence coming off turn. Dirt tracks with medium bite, hard, take a little rubber.

General / Re: What are people's thoughts on the new Afco shocks?
« Last post by legend110 on June 29, 2023, 03:16:10 pm »
Well from what We experienced our last race the new afco shocks dont take a hit like the Bilstein's and the turn around time to repair them is who knows how long so for now holding onto the Bilstein for back up since we still can run either shock for now since all dont have the new shocks yet. Took a hit in the left rear on a start and the afco broke in half on the rod area. At least the Bilstein's would have just bent. The hit was not even straight on it was a side to side hit.

Yes the Nationals here in Nov was a big hit last year with the biggest car count the nationals has had so far. Its a fun few days of racing for sure. My nephew placed top 5 last year during the nationals and it was just his second year in the legends car. Look us up if you decide to come up this way in Nov.
