What Are Common Signs Of A Bad BMW 135i Valve Cover?
You might spot oil seeping out around the top of the engine. Sometimes it pools near where the spark plugs sit. That burnt oil smell when you park or idle? Chances are, it’s coming from a bad BMW 135i valve cover. If your engine runs rough or misfires, oil may be slipping into the spark plug areas. Some folks see a check engine light, often caused by air leaks or issues in the PCV system connected to the BMW 135i valve cover. Notice any of these? Catching them early keeps bigger headaches away.
How Much Does It Cost To Replace A BMW 135i Valve Cover?
Replacement costs for a BMW 135i valve cover can swing pretty wide. Expect to pay $800 to $1,300 at most shops, with about half of that going toward labor. The cover itself runs $400 to $600 for genuine parts, a little lower if you try aftermarket. Labor gets pricey because it’s not a fast job—expect $350 to $700 there. If you know your way around a tool set and have spare time, you could save by doing it yourself. Just make sure you’re comfortable working on a turbo inline-six.
Should I Use Aftermarket Or OEM For My BMW 135i Valve Cover?
When you’re picking a new BMW 135i valve cover, you’ll need to weigh cost and quality. OEM will fit right and usually lasts longer, but your wallet might groan. Some aftermarket covers are cheaper and even outlast originals, especially if they address weak spots like the PCV system. That said, aftermarket quality jumps around. Some are solid, others don’t fit quite right. If you want the safest bet, go OEM. If you’re okay tuning and making tweaks, a high-quality aftermarket BMW 135i valve cover could be a smart move.
Can A BMW 135i Valve Cover Cause Engine Performance Issues?
A bad BMW 135i valve cover can raise all sorts of engine trouble. Cracks or failed gaskets let oil reach the spark plugs, which means misfires and rough idling. A failed PCV valve up top can also make vacuum leaks, leaving your car running weird or throwing engine codes. Ignore it, and you’re risking long-term engine problems. Fixing the valve cover puts your car back in line and helps keep repairs from piling up.
How Long Does It Take To Replace A BMW 135i Valve Cover?
A pro usually needs 3 to 5 hours to swap the BMW 135i valve cover. You’ll have to pull off some intake parts, clean away old sealant, and fit everything back just right. If you’re tackling the job in the garage, block out an afternoon or even a full day, just to play it safe. Along the way, check out the hoses and PCV bits too—swapping old pieces while you’re in there takes care of two jobs at once and might save a future headache.
