What do you guys think about using aftermarket oil coolers? Do they really help with heat management?

They can be beneficial! I installed one, and it reduced my oil temp significantly.

What surprises me is how often these engines spring oil leaks! Any suggestions on fixing them? I have one near the pan.

A good RTV sealant should work for the oil pan. Just make sure surfaces are clean before applying.

I adlibbed a little humor when I had my starter issues—named my engine ‘The Reluctant Performer’! But on a serious note, stay away from cheap starters.

I recommend sticking to a regular maintenance routine every 3,000 miles for oil changes. A good synthetic oil can really help with the longevity of your 350 big block!

That’s solid advice! Also, don’t forget to check the air filter and spark plugs regularly. They can impact your engine’s performance a lot.

Absolutely! And while you’re at it, keep an eye on the coolant levels to prevent overheating. It’s all about that preventive care!

32

Definitely! Does anyone have suggestions for a good coolant product for big block engines?

I’ve had great results with Evans Waterless Coolant—really reduces the risk of corrosion. Just make sure to flush it out properly first!

That’s interesting! How often do you recommend cleaning the injectors?

I’ve had luck with the AC Delco filters. They seem to hold up well in my 350 big block. Just make sure you change it with your oil.

That’s something I didn’t know! I used to just get whatever was on sale. Time to step up my filter game.

You’ll find that good filters can make a huge difference; it’s worth the investment!
