What goes wrong on LS7 and what does it take to fix it?
What goes wrong on LS7 and what does it take to fix it? Ive saw reference to valve issues on the LS7 engine from GM. Is that the only major problem with the engine, and if so what does it take to fix it? (replace the valve guides?) I am going to be replacing my engine, and am half tempted to get an LS7 pull out, but being on the high side of the budget fixing the issue cant be a major expenditure without breaking the budget.
Many thanks!

The most common fix to the valve problem is simply new guides, new exhaust valves, and cutting a new valvejob.
For the sleeve issue, you would need new sleeves.

We do get a lot of LS7 blocks with cracked liners. Depending on your application it would be a good investment to sleeve the block. We offer a couple sleeving options: a dry-sleeve set-up and our Superdeck System.
We also offer fully blueprinted short blocks. Let us know if we can be of any service.

The stock dry sump oiling is garbage. You could convert it to wet sump and change the oil pan to an Fbody which would solve many issues plus be cheaper overall.
If you are just farting around on the street it won't be an issue. If road racing that's where the oiling issues will arise.
It's $2k+ in parts to remedy the issues. Aviad makes the oil pan baffle, external pump, etc.
Katech offers a better pump with billet cover, etc.

Do you get many that are nearly stock? I think my long term goals for the engine would be something very mild, such as a small cam. Hopes being that by going ls7 Id get the displacement and oem redline to make my power for me, not wild builds, turbos, nitrous, or anything of the sort.
