Tapping noise from engine on startup, goes away while idling, then comes back after 2k rpm. Im trying to rule out any expensive issues like rod knock ect and would appreciate if anyone could help me narrow it down. Thanks 🙏

No that is 100% rod knock

Starting off sure, but the longer it goes on the worse it gets

I've got an exact example for you

How long has it been knocking for
Just started has been off the road since it was first heard

Exact same engine if yours is a 3sge

Sound of doom and despair
Be ready for new car, new engine, or rebuild your engine. Don't fuckin crank it anymore if you want a chance at rebuilding it
flint geode
This sounds almost the same and its likely the same motor
3sge's love to spin bearings, so does the 5s
tardy root
I cant lie maybe i got bad ears but that sounds so much deeper and heavier like metal, and it doesnt go away after a couple seconds

Sounds a little different because the engine bay is open in your video but closed in his video

It will have a torched crank already

And mine doesnt increase like pitch when you rev its consistent

Does it speed up with revs
Not pitch, just speed

The second video shows reving

Well done cooked

What I'm sure is happening is that it has bad bearings but still has oil pressure
There's a very easy way to check
Drain the oil and cut the filter
As it does stop likely when it's at oil pressure but this will get worse and worse as it goes on
I've owned 3 personally btw
I bet that filter will be glittery as hell
tardy root
Is there no other way to know? I havnt bought the car yet i was about to pick it up this weekend, it was really cheap so i wanted to fix it up as a project but if it needs a whole new engine it would probably be out of budget
flint geode
Basically oil pressure is rising to fill the gaps in it

An oil change is the cheapest way
It's probably too early for a compression test

Could look for a junkyard motor, if it's na they are mostly cheap
tardy root
Do you know how much a full rebuild would cost for these?
flint geode
3sge/3sfe is like under 500 USD (I don't live in America but it's an economy motor) used
But full rebuild is like 8k
Id just turbo swap atp
I 3sgte swapped mine but the motor isn't rebuilt yet, was about 1.5k USD if I convert

Probably would be in your best interest to drive to pick up a new motor
Shipping is pre costly
tardy root
Okay and how much would it cost for someone to do the swap? I dont have a engine crane or whatever its called, other than that im decent with mechanicing i do motorsport
flint geode
Labor would be thousands possibly
Fixing it yourself is the only way it's worth it
I can't confirm for UK but it's thousands in most countries
In the end it's up to you
tardy root
Yea id do that then
If i can find a cheap enough engine close enough for it to be worth it
Thanks for the help
flint geode
It's a lot of work and you'd also want the car to be rust free
If it's a super rusty car I'd steer clear
Depends on how far you want to go
tardy root
Yea the main reason i didnt mind working with the engine is its shell is in really good condition barely any rust and its only 40k miles compared to much higher for much more expensive im seeing

Pretty much this especially since this is MR. Not a lot of room, axles in the way, etc etc

Just know you need a crane or hoist, this engine comes out the bottom exclusively and then you drop the car on top of it.
