Default How often should you take the engine apart and clean it?

Just as the title says how many hours of use should you wait berfore you do a complete cleaning of the engine internals?

Some people tell me they do it every race, but I'm assuming that means when they complete the weekend right? Not necessarily after each time they run on the track.

I do it every gallon or so of fuel to inspect the internals and clean at the same time. This of course depends on the quality of fuel you are using. If it's something that you are using for the first time, I would recommend to open it after the day of racing to inspect and see the internals. Low quality fuel can gunk the motor in a few tanks.

Cool . And like I said I don't go all out and open my motor after every race day. However, this is just my personal way of doing it which I think is pretty reasonable especially for club racing. If it's the nationals or some big race, then I would inspect the motor after a race day just to check and see if it needs attention.

Yep. I agree. I strip and check every inch of the engine and car after each days running. A well maintained engine always runs better.

What is considered a day's running? Sometimes I will run for an hour...sometimes a couple hours. You know what I mean?

I understand that after a long race day or long day of practice you should and definately I would. However, what about practicing at a local track or club racing? This is what I'm unsure of. I know I can rip it down each time, but I don't think it's necessary that much. Is it seriously?

Basically I'm wondering if you can run a couple hours...do after run maintenance and general cleaning of the car and then run a couple hours next week and be ok?

Its personal preference really. A general days running for me would consist of maybe 20mins practise, 4 x 5min qualifiers and a 30min final. If Im just running the engine on a bench etc I dont bother but if I run the car on the track even for 10mins I strip everything down including the engine. Always better to be save than sorry. Dirt can easily get into the fuel tank when refuelling.

guys, can u actually use water and detergent to wash the engine in-and-outside? i have been wanting to totally clean my engine, but was too afraid that it might not be good with water. so normally, i just use nitro to rinse off the whole engine, which would be very clean as i can't clean the external fins. hmm, i think i shall try it soon.

I like to use kerosine, and a tooth brush to clean engines in and out , then blow them off, i re assemble with parrafin oil. If its a quick job i use a de greaser can then rinse the engine with water, i then blow it off and place it in front of a heat lamp , then i re oil it .. The de greaser has a water protectant in it , it will repel water from the surfaces of the engine..

hmm, i wonder if we can use detergent to clean in & out, then later use air compressor to blow dry, assemble back and lubricate with some after run.

I break my on road motors down about once a month. I keep the outside and the airfilter clean all the time. The frequency that I break the motor down is the same as I clean the chassis. I mean all the way down to the bearings. You will be surprised after a good cleaning to discover cracks and how things have moved.
I use at the track, Simple Green a tooth brush and a good air compressor. Now my off roads.... I clean them everyday I race!

I personally use massivemods way. I clean thoroughly with a small baby toothbrush (soft bristles) with either kerosine or if I dont have any then I use straight fuel. I dont like using air to clean out the motor. It always seems to blow the dirt into the bearings unnoticed. Instead try using 3in1 oil sprayed through a airgun. I prefer leaving the engine soaking in 3in1 oil or equivilent overnight (totally stripped down - put all the separate parts in). That helps dissolve/clear any missed particles trapped in the bearings etc...

I have heard of people using detergent. I havent personally used this but I do know from other applications that you should steer away from powder based detergents like washing powder. The granules act like sandpaper and will at worst leave deep gouges in the case. Use washing liquid if anything. Make sure to rinse well afterwards to get it all removed and then steep the engine in something like 3in1 oil to relubricate and dissolve any missed detergent etc....
