Angry hp oil leak problems

Ok i have a hp oil leak i took the truck to the shop they tested it and found 4 injectors leaking oil at the top they replaced the injectors and put new o rings and checked hp oil pump connection it has the updated connector.but when i got it back the themostat was not working and the truck took 7 to 10 seconds to start cold and after driving it but the themostat not working would not let the engine get to temp so i changed the themostat and the oil and went and drove the truck and with engine at temp it will not start and while changing the oil i noticed the oil i was draining was way thick i think the shop jammed the themostat and put thick oil in to cover up the problem i have a new front cover and lp oilpump.

Im not sure why they would touch the thermostat, you can take the valve covers off without removing the coolant hose. Seems hard to beleive that all the injectors on one side would start to leak oil at the same exact time. But I guess little by little they will eventually give a no start. I always ask for the bad parts if I have someone working on the truck, you never know. I think you need to take it back to the shop and have them check your HPOP pressure and show you the results, if they don't offer to fix for free then tow it somewhere else.
