🔧 Product Description

Genuine Volvo Penta valve seat insert in the 0.20 mm oversize, from the Engine group, weighing 0.023 kg and listed for 27 applications across the TD and TAD engine series. Seat 20580083 carries the same published weight but is the 0.40 mm oversize, so the oversize marking is what tells them apart.

  • Compression loss on one cylinder, with hard starting or a misfire
  • Valve clearances closing up between adjustments
  • Seat burnt, pitted or recessed into the head
  • Insert cracked or loose in its counterbore

🛠️ Service Notes

  • Order by the oversize marking, not by weight - the four seats listed here do not sort by mass
  • Two seats are listed at each oversize, so quote the part number that came out of the head
