Hi everyone. I'm pretty new here - joined a few months ago when I started looking for a 2g. I Finally found one but the engine is knocking. I pulled it last weekend and I'm starting the tear down this week, but I've got a few questions first:
Goal for this car is a cool looking, summer daily. Obviously more power would be nice, but since this is never going to be that impressive, I'm more focused on reliability and maybe even things I can do to improve fuel economy. I know, that's probably never been talked about here, but I figured I'd ask anyway haha.
1. Anything specific to 420a's look out for on the tear down? I've rebuilt several engines, but just wanted to check if there are common internal issues to look out for?
2. I'm following the build guide on 2gNT and it's pretty thorough but there a few questions i've got:
- he spec'ed out PT cruiser lifters and rockers, but didn't say why? I did some research and found that they help with oiling at high rpm. Any opinions on if they are worth it for a street build? I'll have to look into going prices...
posting this here for future folks searching: https://2gnt.com/index.php?d=Rockers
*Edit*
** well, looks like they are all discontinued. Also like $18 piece where you can find the rockers... Maybe junkyards are a good option?
**I wonder how these type replacement lifters do? Maybe cleaning OEM junk yard ones would be better?https://partsology.com/products/set...dbrIu3HaBKXFn-d3WQOBBmLYg5dYG6d8aAptVEALw_wcB
- he talks about a "long rod" setup. How long is it? I'm probably just going to stick with stock rods since I don't plan on boosting it, but a longer rod and higher compression ratio is an interesting thought to boost power a bit. Guessing it's not worth it though unless there are cheap parts that fit?
- Looks like he got most of his parts from Howell Automotive. The site looks like it was made 20yrs ago haha. They still a good source? The standard rebuild option doesn't offer much info of what kind/brand of parts you're getting.
3. I've heard that the stock timing tensioner is trash and should be replaced with a mechanical tensioner. Is that only for boosted/sustained high rpm applications?
That's all I've got for now. Let me know what you'd do for an ideal daily 2GNT build...
Thanks!
