Hello everyone I was driving out over last weekend on the m20 and I was cursing in 4th doing 3000rpm for around 5-10mins to do a DPF RE-GEN and I had my injectors 1,3 blow out my engine head due to the injector bolt failing, I pulled over and popped the bonnet and the engine cover was cracked and had come off its mounts, the engine was smoking white and extremely hot and I had a small fire on the back of the Inlet manifold which slowly died out due to the explosion of diesel spraying all over the engine bay and self combusting

since then I’ve had my car toed back home and a local mobile mechanic come out and drill out the old injector bolts and upgraded for M9 stud Torx bolts with helicoils they done a nice job £300 for 2 hours work.

however on driving the car after i noticed my brakes where shockingly bad! So stoped and opened the bonnet and had a look around and then noticed a small 3-4mm rubber hose had snapped off flush with mating half connector still lodged inside the end of hose. it connectors to the rocker cover on the left hand side of the rocker cover. now I’m no mechanic but with what limited experience I have I’m guessing this is to do with the vacuum system that aids assisted braking and egr actuator etc? is there anyway I can glue this back on or drill a new port and then seal this damaged one up? I’ve just spent £300 getting the injectors done and now I got to spend more to have them all removed and rocker cover replaced and all put back. any suggestions would be appreciated.

after looking back on all the events that led up to the blowout it was me being a cheapskate using a so called mate did a engine service on the car a month or so ago and did a oil change and poured 5 litres of oil in the engine and didn’t check the dipstick level properly I drained 2 litres of oil today by using a oil syringe kit to suck it out through the dip stick tube using a long 6mm pvc tube. He had put so much oil in it had gone over the whole plastic dip and ran about 5cm up the steel wire!!

You were lucky there was a car left. As to the broken pipe maybe drill out and either tap thread and use something like this

Or glue something like this

Reckon if gluing maybe araldite or specific glue for plastic.

Thankyou for your help alasdair1 I have been out today looking over the rocker cover and I was about to do the epoxy glue fix with some JB-weld plastic adhesive (2 part) but I had to clean up all the oil and diesel off top of the engine as I hadn’t got around to cleaning it since it had the new injector bolts installed. I pour some gunk (solvent free) degreaser over the rocker cover and all over the injectors and where all the oil is and then soaked off with 2 buckets of cold water and then I noticed that the water on injectors 1,3 (original ones that blew) the water leaked down implying the seal around them injectors on rocker cover are warped or something I momentarily turned the engine over and saw all the water bubbling around injector 3 and it was obviously leaking so I turned the engine off and called my mechanic who did the repair work on the injectors and he’s going to come out next week and replace the whole rocker cover. I’ve ordered a new rocker cover for it off eBay (parts in motion) a febi cover for £88. And I’ve been quoted £50-£60 to get the new cover on and the injectors fitted back on and torqued etc. I’m very lucky I saw the leak as if I hadn’t been bothered to clean the top of engine I may of never noticed the leak. This would explain why my acceleration was poor in third gear onwards. obv the vacuum pipe being broken off doesn’t help either with the brakes and whatever else the vacuum pipes do. il keep you updated next week how I get on. still if this car don’t work out I still got my trustworthy 2008 1.9 TDI PD fabia2 105bhp hatch, other than the bodywork being poor (rust on boot handle and around rear plate) and lacquer coming off over roof. she’s my old reliable both cars done around the same mileage 126k-128k I paid £1400 for the 1.9 in 2024 and £1570 for the 1.6 in 2025. Mind you with the prices of oil going up I may need not worry about the cars for too long lol 😸

Hopefully just needs new injector seals. I agree with the 1.9tdi. Had a fabia,Seat altea and octavia all with 1.9tdi old school engines with no dpf and less to go wrong. Paid £1800 aprox each and had them for 5 years 160k until dreaded rust became terminal. Still have two sitting for spares and they still run perfectly. Now on a 1.6tdi Octavia mk2 but would swap back tomorow.
