Is there a good chance the exhaust is not leaking when the last stud/bolt is missing?
I can’t see any carbon deposit that would show an exhaust leak (not sure if that would actually happen like that either).
More background:
- new-to-me engine not installed but “was running” according to...
2012 GTI with CBFA engine.
Engine threw a rod a few months ago.
I decided to get a CBFA replacement engine off eBay. I did the timing chains, cleaned up the intake ports (jeez.... much harder than expected! Invest in a walnut blasting equipment! don't waste your time with anything else!)...
2012 autobahn GTI (CBFA engine).
Engine threw a rod, block is cracked.
Body has 120K miles.
Got a used engine of the same type from a CC with roughly same mileage.
What would you do to the engine before installing it? Dead engine was drinking oil like there is no tomorrow (which, I have...
I am DIY'ing an engine replacement on my 2012 GTI w/DSC gearbox.
While I've been DIY'ing everything for many year, replacing an engine will be a first for me.
The replacement engine is similar mileage to the one that died (~120K miles).
I'd like to know if there is a good pointer to:

Thinking about getting a < 120K mile engine.
Where would you source and NOT source an engine from?

The OE part number is 5K0867234CBR2. Can't seem to find it new anymore (the left side is ~$50 new) and the used one are chipped. Technically, I only need the plastic vent that I cracked on mine.....
Closing out this thread with a good news.
After finding out that I had forgotten to secure the air pipe to intake manifold and it separated, I put it back together and the car kept bringing multiple misfires (all cylinders and a generic misfire).
car would have engine start good for ~5s and...
So…. I verified that, engine stopped, I have very good vacuum holding on the evap valve.
however, I can blow into the gas tank without any issue. I thought the gas tank system would be pressurized? Is that because I can’t blow into it (with my lungs) enough to pressurize it?
In term of symptom, beside the codes:
- idle is not the best and jump quite a bit. Check engine light will light up and blink at idle (and disappear if you accelerate).
- if you bring up rpm to 1500+ rpm, you can feel/hear some misfiring, but it’s not that obvious anymore.
Today I discovered that I had not locked the bottom of the air intake so it opened up and must have caused issues since this means that the air intake being measured was incorrect….
i was hopeful and put everything back together.
but, while this helped, this dis not fix the issue.
i can’t...
Nothing is silly! Today I removed and rejnstalled the gas cap. Seal looked fine. Let’s see if the evap code goes away.
Emptied tank, put new/different gas in it and issue did not go away after running the engine for ~1-2 mins. So I’ll rule out the fuel issue for now.
Ok. So today I went back to basics:
- new plugs (old one had a significant layer of carbon/soot on them; thought they had been replaced ~6-9 months ago with the coil pack…. Maybe not? Maybe due to misfire?)
- emptied gas tank and refilled with new gas (could not get a hold of the gas...
So….. looking at the combi valve area, I noticed that I might have forgotten to install (or tighten?) the top bolt. It appears that there is a bolt missing on there. Could that be the cause for the behavior I’m seeing?
not quite sure what the impact is. That might be equivalent to a small...
