It really all depends on if the oil filter is in good working order or if the bypass valve is open.

You should be fine... the engines I was talking about were gummed up really bad, as in chunks came out of the oil pan.

My recommendation is to run half a can of seafoam in the oil for 10-15 minutes before several consecutive oil changes. Its a good cleaner, but its not as strong as the stuff labeled engine flush, so it will clean the engine out at a slower, safer rate.

 

I saw seafoam... It was just too expensive. I bought a bottle of quick flush and didn't use the whole thing.

1. added quick flush to engine oil.

2. Ran engine idle for around the 5 minute mark.

3. drained oil from oil pan around 15 mins.

4. removed old oil filter - replaced with new filter.

5. replaced engine oil with 5.28 quarts 10-30

Just from doing this..... The engine sounded and felt MUCH healthier. I just can't see anything bad happening (hoping). i should change the oil again soon-ish just to make sure that all the flush and debris and shi* has passed. Thus far I have no regrets.

 

Yes, you should definately change the oil again. The last thing you want to do is keep any of the leftover kerosene in the engine because it will start to eat the seals over time.

 

Good idea. I will be changing it asap. Unfortunately I will have to wait until I get my tax money to do it. I now have access to a complete body shop as I am in school trying to get into the trade so I have a complete restoration/refinishing project going on. Do you think that it'll be ok for a week or 2 on the change?

 

I was always told to substitute a quart of ATF for a quart of oil as ATF makes an excellent detergent. Is this safe or should i find something else to put in there?

 

I would say stick with the products that are made for engine flushes. You never know what truly works and what will kill it over time.

 

where can you buy seafoam

 

Autozone

 

According to alot of engine manufactures. They recommend using the specified amount of oil. The 5.2 calls for 5 quarts and thats what I put in it. After I put it in the engine. Its always on the top line of the stick. And its always ran fine. If you put a lil extra in, your not getting the best fuel mileage cause the extra oil is creating a drag. Even if you add a lil, you won't do any damage to anything.

 

good to know. I'm going to change the oil again anyway and I'm going with amzoil so 4 quarts is almost 9 bucks cheaper.

Also, I've heard about going up to thicker weight oils based on mileage due to engine wear, a guy told me I should use 10-40 rather than 10-30. Have you heard of this?
